Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) narrates that during the caliphate of Sayyiduna Abu Bakr (may Allah be pleased with him), the Companions compiled the Noble Qur'an in the form of a Mushaf. People would write, and Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) would dictate to them. When they reached this verse of Surah Bara'ah {ثُمَّ انْصَرَفُوْا صَرَفَ اللّٰہُ قُلُوبَہُمْ بِأَ نَّہُمْ قَوْمٌ لَا یَفْقَہُونَ} … then they turn back. Allah has turned their hearts, because indeed they are a people who do not understand. They thought that this was the last verse of the Surah, but Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) said to them that the Noble Prophet (peace and blessings be upon him) had taught me these two verses after it: {لَقَدْ جَائَ کُمْ رَسُوْلٌ مِّنْ اَنْفُسِکُمْ عَزِیْزٌ عَلَیْہِ مَا عَنِتُّمْ حَرِیْصٌ عَلَیْکُمْ بِالْمُؤْمِنِیْنَ رَئُ وْفٌ رَّحِیْمٌ۔ فَاِنْ تَوَلَّوْا فَقُلْ حَسْبِیَ اللّٰہُ لَآ اِلٰہَ اِلَّا ھُوَ عَلَیْہِ تَوَکَّلْتُ وَھُوَ رَبُّ الْعَرْشِ الْعَظِیْمِ۔} … Surely there has come to you a Messenger from among yourselves; it grieves him that you should suffer; he is full of concern for you, and is kind and merciful to the believers. But if they turn away, say: Allah is sufficient for me; there is no deity except Him; in Him I have put my trust, and He is the Lord of the Mighty Throne. Then he said: This part of the Qur'an was revealed at the very end. Then he said: Thus, the religion was concluded with the same Tawheed with which it was begun; by this he meant "Allah, there is no deity except Him," and that is the statement of Allah the Exalted: {وَمَا أَ رْسَلْنَا مِنْ قَبْلِکَ مِنْ رَسُولٍ إِلَّا یُوحَی إِلَیْہِ أَ نَّہُ لَا اِلٰہَ إِلَّا أَ نَا فَاعْبُدُونِ} … And We did not send any Messenger before you except that We revealed to him that there is no deity except Me, so worship Me. (According to the mentioned narration, the word in the verse of the Noble Qur'an is "yuha ilayhi" — it was revealed to him (every Messenger). Whereas in our well-known recitation, it is "nuhi ilayhi" — We reveal to him. (Abdullah Rafiq))
