The opening describes the disbelievers among the People of the Book and the associators as not leaving their disbelief until the clear proof came to them. مُنْفَكّ۪ينَ concerns their separation from what they held, and حَتّٰى تَأْتِيَهُمُ الْبَيِّنَةُ marks the arrival without which they would not leave it. This does not require every one of them to believe once it arrives: the sūrah goes on to distinguish their responses. Elsewhere, the sending of Messengers ends the plea that no bearer of good news or warning came. Here the decisive arrival is likewise a Messenger bringing revelation.

The clear proof is named: رَسُولٌ مِنَ اللّٰهِ يَتْلُوا صُحُفًا مُطَهَّرَةًۙ ف۪يهَا كُتُبٌ قَيِّمَةٌ. It comes as a Messenger from Allah reciting the contents of purified pages, within which are upright writings. Purity excludes falsehood; uprightness describes the truth of what is written. The recitation makes that revelation heard. Elsewhere the Messenger’s mission likewise includes reciting Allah’s verses and teaching the Book, while the Reminder is described as held in honored, raised, purified pages. Written preservation and living recitation belong to the same divine gift.

The clear proof returns in the account of division: وَمَا تَفَرَّقَ الَّذ۪ينَ اُو۫تُوا الْكِتَابَ اِلَّا مِنْ بَعْدِ مَا جَٓاءَتْهُمُ الْبَيِّنَةُ. Those given the Book divided only after the proof had come. Their possession of revelation did not prevent disagreement over the truth it disclosed. The Qur’an elsewhere warns believers not to become like those who divided after clear proofs, and joins the command to establish religion to the prohibition of fragmenting it. Clarity supplies a ground for agreement; its arrival does not make obedience automatic.

The next verse makes that division more grievous: their own scriptures had commanded them to worship Allah with devotion wholly His. Yūsuf likewise contrasts many lords with Allah, the One, declares that worship belongs to Him alone, and names this the upright religion. Al-Rūm joins turning toward the religion without associating partners, establishing prayer, and refusing the divisions of those who fragment their religion into factions. The unity sought is shared obedience to the one God.

The command is لِيَعْبُدُوا اللّٰهَ مُخْلِص۪ينَ لَهُ الدّ۪ينَ حُنَفَٓاءَ. They are to worship Allah with their religion devoted exclusively to Him, turning away from association and toward Him alone. This is more than a sincere feeling that could accompany worship of any object. Elsewhere, the Prophet is guided to the creed of Ibrāhīm and declares that his prayer, sacrifice, life, and death belong to Allah alone. Another passage rejects the claim that worshipping intermediaries is a way to draw nearer to Him. Al-Bayyinah calls for devotion whose sincerity includes the exclusion of rivals.

That devotion includes وَيُق۪يمُوا الصَّلٰوةَ وَيُؤْتُوا الزَّكٰوةَ: establishing prayer and giving the prescribed alms. The verse does not leave exclusive worship as an inward intention without acts. Prayer is established, and the due of wealth is paid. Together with devotion to Allah alone, these are named د۪ينُ الْقَيِّمَةِ, the upright religion. The earlier كُتُبٌ قَيِّمَةٌ thus finds a corresponding description in the life it commands. Upright revelation seeks an upright human life.

The same conjunction appears where those who believe, do righteous deeds, establish prayer, and give the prescribed alms are promised their reward with their Lord. It illuminates the movement here from the command in 98:5 to faith, deeds, and reward in 98:7–8. Prayer and giving are not detachable additions to the sūrah’s account of faith; they are specified acts within the obedience for which the believers are praised.

The judgment returns to those who disbelieved among the People of the Book and the associators, then sets beside them اِنَّ الَّذ۪ينَ اٰمَنُوا وَعَمِلُوا الصَّالِحَاتِ—those who believe and do righteous deeds. Al-ʿImrān says that among the People of the Book are those who believe in Allah, in the Qur’an sent down to the Muslims, and in the scriptures sent down to themselves. They humble themselves before Allah and do not trade His verses for a small price. They too are promised their reward with their Lord.

The opposed verdicts are emphatic: اُو۬لٰٓئِكَ هُمْ شَرُّ الْبَرِيَّةِ and اُو۬لٰٓئِكَ هُمْ خَيْرُ الْبَرِيَّةِ—the worst and the best of creation. Al-Tīn likewise places the human’s excellent formation beside the lowest abasement, then excepts those who believe and do righteous deeds. Here that same description identifies the best of creation.

The warning is severe: those who disbelieve will abide in the Fire of Hell. The promise then opens outward: جَزَٓاؤُ۬هُمْ عِنْدَ رَبِّهِمْ—their reward with their Lord is gardens of lasting dwelling, with rivers flowing beneath them. There they will abide forever. Beyond this comes رَضِيَ اللّٰهُ عَنْهُمْ وَرَضُوا عَنْهُ: Allah is pleased with them, and they are pleased with Him. His approval accompanies their delight in what He has bestowed. The same formula follows gardens and endless abiding in Al-Māʾidah, where it is named the great triumph. The reward is not merely possession of gifts, but the joy of receiving them from the Lord who is pleased with His servants.

The last words identify the recipient of that promise: ذٰلِكَ لِمَنْ خَشِيَ رَبَّهُ—“That is for whoever fears his Lord.” This fear moves the servant to obey Him and turn away from sin. In Fāṭir, those who fear their Lord unseen and establish prayer are the ones who benefit from warning. Al-Mulk promises forgiveness and a great reward to those who fear Him unseen. The Lord whom they fear is the Lord whose approval they receive.
