The expedition is ending, but revelation has not finished its work. Those who preferred to remain behind prepare another defense when the Prophet and his companions return to them: يَعْتَذِرُونَ اِلَيْكُمْ اِذَا رَجَعْتُمْ اِلَيْهِمْۜ. The Prophet is told to answer, قُلْ لَا تَعْتَذِرُوا لَنْ نُؤْمِنَ لَكُمْ قَدْ نَبَّاَنَا اللّٰهُ مِنْ اَخْبَارِكُمْۜ. Do not offer excuses; we will not believe you, for God has informed us about you. Yet their future conduct still matters: وَسَيَرَى اللّٰهُ عَمَلَكُمْ وَرَسُولُهُ. Earlier, lack of preparation exposed unwillingness beneath the claim of inability. What they do next will show whether they persist in hypocrisy or repent. Even then the case does not end with what human beings can observe: ثُمَّ تُرَدُّونَ اِلٰى عَالِمِ الْغَيْبِ وَالشَّهَادَةِ فَيُنَبِّئُكُمْ بِمَا كُنْتُمْ تَعْمَلُونَ. Final disclosure and recompense belong to the Knower of the unseen and the witnessed.

The desired outcome is stated again as approval: يَحْلِفُونَ لَكُمْ لِتَرْضَوْا عَنْهُمْۚ. Even if believers become satisfied, فَاِنَّ اللّٰهَ لَا يَرْضٰى عَنِ الْقَوْمِ الْفَاسِق۪ينَ: God does not approve of people persisting in rebellion. Human approval cannot shelter them from His displeasure. The contrast reaches back to the promise that God’s approval is greater than the delights of the Garden, and forward to those with whom He is pleased and who are pleased with Him. These oath-takers seek people's approval while refusing the obedience that would please God.

The view widens to the Bedouins. Unbelief and hypocrisy are more severe among them, and they are more liable not to know the limits revealed to the Messenger: life far from his teaching can deepen that ignorance. Yet the next verses distinguish people within this setting. Some treat what they spend as مَغْرَمًا, an unrewarded loss, and wait for calamity to strike the believers. The wished-for calamity is turned back upon them. Others believe in God and the Last Day and seek through their spending قُرُبَاتٍ عِنْدَ اللّٰهِ وَصَلَوَاتِ الرَّسُولِۜ—nearness to God and the Messenger’s prayers for them. God confirms their hope: اَلَٓا اِنَّهَا قُرْبَةٌ لَهُمْۜ. Their giving truly brings them near, and He will admit them into His mercy. Earlier some gave only with aversion; here believing generosity receives an emphatic promise from the Forgiving, the Merciful.

The sūrah then honors the first forerunners among the emigrants and helpers, and those who follow them in goodness: وَالسَّابِقُونَ الْاَوَّلُونَ مِنَ الْمُهَاجِر۪ينَ وَالْاَنْصَارِ وَالَّذ۪ينَ اتَّبَعُوهُمْ بِاِحْسَانٍۙ. Their early faith and service become an example others can follow. Then comes رَضِيَ اللّٰهُ عَنْهُمْ وَرَضُوا عَنْهُ: God is pleased with their obedience, and they are pleased with the bounty He grants them. Elsewhere the same mutual pleasure belongs to the truthful on the day their truth benefits them. Here God has prepared gardens with flowing rivers, where they remain forever. The great triumph is both promised to those who went before and opened to those who faithfully follow.

Yet among the Bedouins around Madinah, and within Madinah itself, there are concealed hypocrites. Some have become so practiced in concealment that the Prophet is told: لَا تَعْلَمُهُمْۜ نَحْنُ نَعْلَمُهُمْۜ. You do not know them; We know them. The sūrah exposes much, but it does not give the community unrestricted knowledge of hidden hearts. Elsewhere God distinguishes the corrupt from the good while reserving disclosure of the unseen to messengers He chooses. Here He knows the hypocrisy still hidden from His Messenger and announces two punishments before their return to the tremendous punishment of the Fire. Their concealment from people does not conceal them from Him.

Against excuse stands confession: وَاٰخَرُونَ اعْتَرَفُوا بِذُنُوبِهِمْ. Others acknowledge their sins. They are not simply another group of concealed hypocrites: خَلَطُوا عَمَلًا صَالِحًا وَاٰخَرَ سَيِّئًاۜ. They have mixed good conduct with bad, and their acknowledgment is itself a movement toward repair. God opens hope to them: عَسَى اللّٰهُ اَنْ يَتُوبَ عَلَيْهِمْۜ. This is reassurance from the One who immediately names Himself Forgiving and Merciful. Elsewhere those who wrong themselves remember God, seek forgiveness, and refuse to persist knowingly. Here honest acknowledgment meets the promise of acceptance; failure need not become a life spent defending it.

Confession is followed by repair through giving. The Prophet is commanded, خُذْ مِنْ اَمْوَالِهِمْ صَدَقَةً تُطَهِّرُهُمْ وَتُزَكّ۪يهِمْ بِهَا وَصَلِّ عَلَيْهِمْۜ. Through a charitable contribution from their wealth, he is to cleanse them of sin and help them grow in goodness, and he is to pray for them. اِنَّ صَلٰوتَكَ سَكَنٌ لَهُمْۜ: his prayer brings reassurance that they have been accepted. Earlier funeral prayer was barred for those who died in unbelief; here prayer for living penitents strengthens their hope. The believing Bedouins sought the Messenger’s prayers through giving. These confessing believers now receive the same care.

The next verse grounds that reassurance in God’s own acceptance: اَلَمْ يَعْلَمُٓوا اَنَّ اللّٰهَ هُوَ يَقْبَلُ التَّوْبَةَ عَنْ عِبَادِه۪ وَيَأْخُذُ الصَّدَقَاتِ. The Prophet takes their contribution; God accepts their giving and their repentance. What passes from their hands is received with favor by Him. Elsewhere wrongdoers who come to the Messenger, seek God’s forgiveness, and receive the Messenger’s prayer find God accepting of repentance and merciful. Here that assurance is renewed emphatically: وَاَنَّ اللّٰهَ هُوَ التَّوَّابُ الرَّح۪يمُ. The people who confessed their wrong are not left to guess whether their return has reached Him.

The assurance that God accepts repentance is followed by a command to act: وَقُلِ اعْمَلُوا فَسَيَرَى اللّٰهُ عَمَلَكُمْ وَرَسُولُهُ وَالْمُؤْمِنُونَۜ. God will see their deeds, and so will His Messenger and the believers. The call is to good works after repentance, with encouragement to obey and warning against renewed wrongdoing. As at the opening of the passage, their final return is to عَالِمِ الْغَيْبِ وَالشَّهَادَةِ, the Knower of the unseen and the witnessed. He will tell them what they did and reward or punish them accordingly. The invitation to begin again remains an invitation to accountable action.

Others must still wait: وَاٰخَرُونَ مُرْجَوْنَ لِاَمْرِ اللّٰهِ. Their case is deferred to God’s command, اِمَّا يُعَذِّبُهُمْ وَاِمَّا يَتُوبُ عَلَيْهِمْۜ—whether He punishes them or turns toward them in mercy. These are the three sincere believers whose absence was a real wrong, but whose truthful acknowledgment was not yet followed by an announced pardon. Their resolution will come later in the sūrah. Here the deferred men wait in hope and fear upon the judgment of the Knowing, the Wise.

The next exposure concerns a building. A structure called a mosque has been established مَسْجِدًا ضِرَارًا وَكُفْرًا وَتَفْر۪يقًا بَيْنَ الْمُؤْمِن۪ينَ وَاِرْصَادًا لِمَنْ حَارَبَ اللّٰهَ وَرَسُولَهُ مِنْ قَبْلُۜ: to harm believers, support unbelief, divide their community, and provide a base for one who had already fought God and His Messenger. Its founders swear, اِنْ اَرَدْنَٓا اِلَّا الْحُسْنٰىۜ—we intended only good. Elsewhere hypocrites evade God’s judgment and then swear that they wanted only good and reconciliation. Here too the claimed intention cannot stand against what God reveals of their purpose. A structure built to divide does not become sacred because its builders give the division a beautiful name. وَاللّٰهُ يَشْهَدُ اِنَّهُمْ لَكَاذِبُونَ: God bears witness that they are lying.

The Prophet is told, لَا تَقُمْ ف۪يهِ اَبَدًاۜ: never stand in prayer there. His prayer would lend his presence to a purpose God has condemned. The alternative is identified by its foundation: لَمَسْجِدٌ اُسِّسَ عَلَى التَّقْوٰى مِنْ اَوَّلِ يَوْمٍ اَحَقُّ اَنْ تَقُومَ ف۪يهِۜ. A mosque founded from its first day upon reverence and obedience to God is worthy of his prayer. Within it are men who love to purify themselves, including the bodily cleansing that prepares them for worship, and وَاللّٰهُ يُحِبُّ الْمُطَّهِّر۪ينَ—God loves those who purify themselves. Elsewhere His love joins repentance and purification. Here the foundation and the worshippers agree: their desire for purity meets His love.

The comparison strips architecture down to what bears it: اَفَمَنْ اَسَّسَ بُنْيَانَهُ عَلٰى تَقْوٰى مِنَ اللّٰهِ وَرِضْوَانٍ خَيْرٌ. Is the one who builds upon fear of God and the pursuit of His approval better, or the one who builds عَلٰى شَفَا جُرُفٍ هَارٍ فَانْهَارَ بِه۪ ف۪ي نَارِ جَهَنَّمَۜ—on the edge of a crumbling bank that collapses with him into Hell? The two foundations picture the difference between obedient faith and concealed unbelief. Āl ʿImrān told believers that God joined hostile hearts, made them brothers, and rescued them from the brink of a pit of fire. Here a mosque built تَفْر۪يقًا بَيْنَ الْمُؤْمِن۪ينَ, to divide believers, works against that joining. The repeated brink-image gives the contrast its terrible direction: what claims to house worship may carry its builder toward the Fire.

The demolished building leaves something standing in its builders: لَا يَزَالُ بُنْيَانُهُمُ الَّذ۪ي بَنَوْا ر۪يبَةً ف۪ي قُلُوبِهِمْ اِلَّٓا اَنْ تَقَطَّعَ قُلُوبُهُمْۜ. Its destruction deepens their resentment and doubt about the Messenger. What they built remains a source of distrust until their hearts are torn apart in death. Earlier sacred maintenance could not vindicate unbelief. Here even the loss of the false mosque does not bring its founders to relinquish it inwardly.

From the false building, the passage moves to the true transaction: اِنَّ اللّٰهَ اشْتَرٰى مِنَ الْمُؤْمِن۪ينَ اَنْفُسَهُمْ وَاَمْوَالَهُمْ بِاَنَّ لَهُمُ الْجَنَّةَۜ. God has purchased from the believers their selves and wealth in return for the Garden. He created those selves and provided that wealth, yet honors their surrender with the language of purchase and a promised reward. Elsewhere one sells his self seeking God’s approval, and the pledge given to the Messenger is named a pledge to God. Here the price is not a small worldly gain: the Garden is promised to them. The transaction calls for surrender, but its announcement invites joy.

The battlefield clause includes both action and vulnerability: they fight in God’s way, فَيَقْتُلُونَ وَيُقْتَلُونَ—killing and being killed. Both belong within the promise; it does not require every fighter to kill or be killed. The promise is binding, affirmed in the Torah, Gospel, and Qur’an: وَعْدًا عَلَيْهِ حَقًّا فِي التَّوْرٰيةِ وَالْاِنْج۪يلِ وَالْقُرْاٰنِۜ. Then comes وَمَنْ اَوْفٰى بِعَهْدِه۪ مِنَ اللّٰهِ: who is more faithful to His covenant than God? The sūrah has exposed cheap exchanges of revelation and promises to give that failed when wealth arrived. Now His faithfulness answers human betrayal. Believers are told to rejoice in the sale they have made: the costly surrender is the great triumph.

The next verse describes the fullness of believing life. It begins اَلتَّٓائِبُونَ الْعَابِدُونَ الْحَامِدُونَ—those who repent, worship, and praise God—then السَّٓائِحُونَ, those who fast, followed by those who bow and prostrate, command right and forbid wrong. It closes with وَالْحَافِظُونَ لِحُدُودِ اللّٰهِۜ, those who guard God’s limits. The believer is not defined by combat alone. Repentance, worship, bodily discipline, and responsibility toward others belong to the same faithful life. Earlier some Bedouins were described as especially liable not to know the revealed limits; these believers guard them. The final command is to give the believers glad tidings.

The boundary of seeking forgiveness reaches even kinship. مَا كَانَ لِلنَّبِيِّ وَالَّذ۪ينَ اٰمَنُٓوا اَنْ يَسْتَغْفِرُوا لِلْمُشْرِك۪ينَ وَلَوْ كَانُٓوا اُو۬ل۪ي قُرْبٰى مِنْ بَعْدِ مَا تَبَيَّنَ لَهُمْ اَنَّهُمْ اَصْحَابُ الْجَح۪يمِ. The Prophet and believers may not seek forgiveness for idolaters once it is clear that they belong to the Fire, even if they are close relatives. Death in unbelief establishes that end; revelation may also disclose it. The condition is not a person's private suspicion about another. Earlier family bonds could not override allegiance to God. Here they cannot overturn a final judgment, although hope for a living person's guidance remains distinct from asking forgiveness after that final refusal is known.

Abraham supplies the clarifying scene. وَمَا كَانَ اسْتِغْفَارُ اِبْرٰه۪يمَ لِاَب۪يهِ اِلَّا عَنْ مَوْعِدَةٍ وَعَدَهَٓا اِيَّاهُۚ. His prayer for his father arose from a promise he had made before his father's final refusal became clear. Then فَلَمَّا تَبَيَّنَ لَهُٓ اَنَّهُ عَدُوٌّ لِلّٰهِ تَبَرَّاَ مِنْهُۜ: when he knew that his father remained an enemy to God, he disavowed him and ceased seeking his forgiveness. The sūrah’s opening بَرَٓاءَةٌ finds a related expression here in Abraham’s disavowal. Yet he is still لَاَوَّاهٌ حَل۪يمٌ, tenderly prayerful and forbearing. Elsewhere he pleads concerning Lot’s people until God’s command ends the plea; elsewhere too his promise to seek forgiveness for his father is excepted from the example believers are told to follow. His tenderness explains the promise; clarification explains why he ceased.

Clarification also brings reassurance: وَمَا كَانَ اللّٰهُ لِيُضِلَّ قَوْمًا بَعْدَ اِذْ هَدٰيهُمْ حَتّٰى يُبَيِّنَ لَهُمْ مَا يَتَّقُونَۜ. God does not declare a guided people astray for breaking a prohibition before He has made it clear to them. Those who sought forgiveness before this boundary was explained are not treated as knowingly defying it. The declaration that God knows all things supports that assurance. Then His dominion is affirmed: اِنَّ اللّٰهَ لَهُ مُلْكُ السَّمٰوَاتِ وَالْاَرْضِۜ يُحْي۪ وَيُم۪يتُۜ. He owns the heavens and earth, gives life and death, and is their only protector and helper: وَمَا لَكُمْ مِنْ دُونِ اللّٰهِ مِنْ وَلِيٍّ وَلَا نَص۪يرٍ. Relinquishing a forbidden allegiance does not leave believers without protection; it directs them to its true source.

God’s pardon reaches the heart of the faithful community: لَقَدْ تَابَ اللّٰهُ عَلَى النَّبِيِّ وَالْمُهَاجِر۪ينَ وَالْاَنْصَارِ. He has turned in mercy toward the Prophet and the emigrants and helpers who followed him in the hour of hardship. The difficulty of Tabuk was real, and some almost faltered in their determination to accompany him: مِنْ بَعْدِ مَا كَادَ يَز۪يغُ قُلُوبُ فَر۪يقٍ مِنْهُمْ ثُمَّ تَابَ عَلَيْهِمْۜ. The people who answered the summons are not beyond the need for His forgiveness and sustaining mercy. Āl ʿImrān teaches guided believers to ask God to keep their hearts from deviating and to grant them mercy. Here He declares that He has turned toward those who nearly faltered: اِنَّهُ بِهِمْ رَؤُ۫فٌ رَح۪يمٌۙ—He is compassionate and merciful to them.

His mercy extends وَعَلَى الثَّلٰثَةِ الَّذ۪ينَ خُلِّفُواۜ—to the three whose cases were deferred. They had admitted their unjustified absence and awaited God’s judgment while the community withheld ordinary contact. Their distress reaches from the world around them into their own selves: حَتّٰٓى اِذَا ضَاقَتْ عَلَيْهِمُ الْاَرْضُ بِمَا رَحُبَتْ وَضَاقَتْ عَلَيْهِمْ اَنْفُسُهُمْ. The broad earth feels narrow, and they find no relief within themselves. The earth-image returns from Hunayn, where constriction was followed by retreat; the false claimants would have rushed toward any refuge or cave. These three recognize instead وَظَنُّٓوا اَنْ لَا مَلْجَاَ مِنَ اللّٰهِ اِلَّٓا اِلَيْهِۜ: there is no refuge from God except with Him, through seeking His forgiveness and turning to Him. Their distress does not end in flight from Him. It ends in knowing where refuge lies.

The sentence then joins their return to God’s initiative: ثُمَّ تَابَ عَلَيْهِمْ لِيَتُوبُواۜ. He turns toward them so that they may repent, granting the help by which they return. Their honest acknowledgment and grief are not erased; they are met and sustained by His mercy. Adam too received words from his Lord, and God accepted his repentance. Here the deferred judgment finally opens into acceptance: اِنَّ اللّٰهَ هُوَ التَّوَّابُ الرَّح۪يمُ۟. He is the One who repeatedly accepts repentance, the Merciful.

The command that follows is not merely “speak truth”: يَٓا اَيُّهَا الَّذ۪ينَ اٰمَنُوا اتَّقُوا اللّٰهَ وَكُونُوا مَعَ الصَّادِق۪ينَ. Be with the truthful, sharing their truthfulness in intention, word, and deed. The three did not save themselves by constructing better excuses; they told the truth and were received in mercy. Elsewhere the truthful benefit from their truth, and believers who fulfill their covenant are praised for not altering it. Here truthfulness becomes both conduct and company: those who believe are called to live with, and live like, the truthful.

The people of Madinah and the Bedouins around them may not leave the Messenger to undertake the expedition without them or وَلَا يَرْغَبُوا بِاَنْفُسِهِمْ عَنْ نَفْسِه۪ۜ—prefer their own selves to his, protecting their ease while leaving him to bear hardship. The sūrah will end by describing his care in the other direction: their hardship is grievous to him, and he is intensely solicitous for them. They must not withhold themselves from the burden he carries; he feels deeply the burden that reaches them. His willingness to share hardship gives their attempted exemption its particular ugliness.

The promise enters the body: لَا يُص۪يبُهُمْ ظَمَاٌ وَلَا نَصَبٌ وَلَا مَخْمَصَةٌ ف۪ي سَب۪يلِ اللّٰهِ. No thirst, fatigue, or hunger reaches them in God’s way, nor do they tread ground that enrages the unbelievers or inflict a loss upon an enemy, without a righteous deed being recorded for them. The next verse includes every contribution, صَغ۪يرَةً وَلَا كَب۪يرَةً, small or large, and every valley crossed. God records them to grant the finest recompense for their deeds. Earlier nothing could strike believers except what God had written for them; now what they bear in obedience is also written to their credit. The record holds not only what they achieve, but what they expend, suffer, and traverse. Elsewhere God's promise not to lose a worker's deed likewise embraces migration, injury, fighting, and being killed. Even the small contribution mocked by hypocrites is held in a record no mockery can diminish.

Then comes the necessary differentiation: وَمَا كَانَ الْمُؤْمِنُونَ لِيَنْفِرُوا كَٓافَّةًۜ. Believers are not all to depart together. When the Messenger sends an expedition while remaining himself, some go and others stay with him to learn the religion. Those who learn then warn their people when the travelers return: لِيَتَفَقَّهُوا فِي الدّ۪ينِ وَلِيُنْذِرُوا قَوْمَهُمْ اِذَا رَجَعُٓوا اِلَيْهِمْ لَعَلَّهُمْ يَحْذَرُونَ۟. The earlier summons to readiness does not make everyone’s assignment identical. The community needs both those who undertake its expeditions and those who preserve and teach what God reveals.

Al-Aḥqāf shows a group of jinn listening attentively to the Qur’an and then returning to their people as warners. What they have heard must reach those who were not there to hear it. Here, too, learning the religion leads to warning others, so that they may guard themselves against disobedience.

The command to fight returns: قَاتِلُوا الَّذ۪ينَ يَلُونَكُمْ مِنَ الْكُفَّارِ وَلْيَجِدُوا ف۪يكُمْ غِلْظَةًۜ. Believers are to fight the unbelievers nearest to them, who must find them firm in battle. The geographical priority gives order to the campaign: do not leave the nearer enemy behind while reaching for the farther one. The assurance is the same as before: وَاعْلَمُٓوا اَنَّ اللّٰهَ مَعَ الْمُتَّق۪ينَ. God is with those who revere and obey Him, granting protection and help. Firmness belongs to that obedience; it does not cancel the covenants and protections the sūrah has expressly retained.

At the end, the sūrah turns to the reception of revelation: وَاِذَا مَٓا اُنْزِلَتْ سُورَةٌ. Whenever a sūrah is sent down, some hypocrites ask mockingly whose faith it has increased. God answers: فَاَمَّا الَّذ۪ينَ اٰمَنُوا فَزَادَتْهُمْ ا۪يمَانًا وَهُمْ يَسْتَبْشِرُونَ. Believers grow in faith and rejoice at its coming. For diseased hearts, it adds رِجْسًا اِلٰى رِجْسِهِمْ—further hypocrisy to what is already there, until they die in unbelief. The revelation is one; the increases are opposite. Elsewhere recited verses increase believers in faith, and they trust their Lord; the Qur’an brings healing and mercy to believers but deepens the loss of those who reject it. The hypocrites’ question is answered by the very contrast it tried to dismiss.

The final act of refusal is almost silent. When a sūrah is recited in their presence, نَظَرَ بَعْضُهُمْ اِلٰى بَعْضٍۜ هَلْ يَرٰيكُمْ مِنْ اَحَدٍ ثُمَّ انْصَرَفُواۜ. They exchange looks, check whether any believer sees them, and slip away. Their departure is answered by صَرَفَ اللّٰهُ قُلُوبَهُمْ بِاَنَّهُمْ قَوْمٌ لَا يَفْقَهُونَ: God turns their hearts away from faith because they are people who do not understand. Al-Saff likewise joins persistent deviation to God’s turning hearts from the truth. The contrast within Al-Tawbah is stark. The three acknowledged their failure and found refuge with God; these hearers seek escape from His revelation. Both have faced exposure, but they turn in opposite directions.

Then, after so many people have tried to escape the Messenger’s command, the sūrah presents the Messenger from whom they turn: لَقَدْ جَٓاءَكُمْ رَسُولٌ مِنْ اَنْفُسِكُمْ. A Messenger has come to you from among yourselves; عَز۪يزٌۘ عَلَيْهِ مَا عَنِتُّمْ حَر۪يصٌ عَلَيْكُمْ: what burdens and afflicts you is grievous to him, and he is intensely solicitous for you. His concern is for their faith and well-being, including deliverance from the punishment rejection brings. Āl ʿImrān described enemies who desire the believers’ hardship; what they desire, he finds hard to bear. Toward believers he is بِالْمُؤْمِن۪ينَ رَؤُ۫فٌ رَح۪يمٌ, compassionate and merciful. The earlier insult “he is an ear” receives its fullest answer here. His merciful hearing and the demanding summons belong to the same concern for their good.

If they nevertheless turn away, the Messenger is given words of sufficiency: فَاِنْ تَوَلَّوْا فَقُلْ حَسْبِيَ اللّٰهُۘ. Say: God is sufficient for me. The people displeased with their allotment should have said حَسْبُنَا اللّٰهُ; believers facing what God decrees were commanded to trust Him. Now the Messenger confesses لَٓا اِلٰهَ اِلَّا هُوَۜ عَلَيْهِ تَوَكَّلْتُ: there is no god but Him; upon Him I have relied. Their rejection does not leave him without help. The closing title gives that reliance its scale: وَهُوَ رَبُّ الْعَرْشِ الْعَظ۪يمِ, Lord of the tremendous Throne. Elsewhere that Lord is the One who grants protection while none can protect against Him. The sūrah ends with a compassionate Messenger sustained by a Lord whose power exceeds the refusal he faces.
