My uncle, you just make a profession that there is no god but Allah, and I will bear testimony before Allah (of your being a believer), Abu Jahl and 'Abdullah b. Abi Umayya addressing him said: Abu Talib, would you abandon the religion of 'Abdul-Muttalib? The Messenger of Allah ﷺ constantly requested him (to accept his offer), and (on the other hand) was repeated the same statement (of Abu Jahl and 'Abdullah b. Abi Umayya) till Abu Talib gave his final decision and be stuck to the religion of 'Abdul-Muttalib and refused to profess that there is no god but Allah. Upon this the Messenger of Allah remarked: By Allah, I will persistently beg pardon for you till I am forbidden to do so (by God), It was then that Allah, the Magnificent and the Glorious, revealed this verse: " It is not meet for the Prophet and for those who believe that they should beg pardon for the polytheists, even though they were their kith and kin, after it had been made known to them that they were the denizens of Hell" (ix. 113) And it was said to the Messenger of Allah ﷺ: " Verily thou canst not guide to the right path whom thou lovest. And it is Allah Who guideth whom He will, and He knoweth best who are the guided" (xxviii, 56).  

لَمَّا حَضَرَتْ أَبَا طَالِبٍ الْوَفَاةُ جَاءَهُ رَسُولُ اللَّهِ ﷺ فَوَجَدَ عِنْدَهُ أَبَا جَهْلٍ وَعَبْدَ اللَّهِ بْنَ أَبِي أُمَيَّةَ بْنِ الْمُغِيرَةِ فَقَالَ رَسُولُ اللَّهِ ﷺ يَا عَمِّ قُلْ لاَ إِلَهَ إِلاَّ اللَّهُ كَلِمَةً أَشْهَدُ لَكَ بِهَا عِنْدَ اللَّهِ فَقَالَ أَبُو جَهْلٍ وَعَبْدُ اللَّهِ بْنُ أَبِي أُمَيَّةَ يَا أَبَا طَالِبٍ أَتَرْغَبُ عَنْ مِلَّةِ عَبْدِ الْمُطَّلِبِ فَلَمْ يَزَلْ رَسُولُ اللَّهِ ﷺ يَعْرِضُهَا عَلَيْهِ وَيُعِيدُ لَهُ تِلْكَ الْمَقَالَةَ حَتَّى قَالَ أَبُو طَالِبٍ آخِرَ مَا كَلَّمَهُمْ هُوَ عَلَى مِلَّةِ عَبْدِ الْمُطَّلِبِ وَأَبَى أَنْ يَقُولَ لاَ إِلَهَ إِلاَّ اللَّهُ فَقَالَ رَسُولُ اللَّهِ ﷺ أَمَا وَاللَّهِ لأَسْتَغْفِرَنَّ لَكَ مَا لَمْ أُنْهَ عَنْكَ فَأَنْزَلَ اللَّهُ ﷻ { مَا كَانَ لِلنَّبِيِّ وَالَّذِينَ آمَنُوا أَنْ يَسْتَغْفِرُوا لِلْمُشْرِكِينَ وَلَوْ كَانُوا أُولِي قُرْبَى مِنْ بَعْدِ مَا تَبَيَّنَ لَهُمْ أَنَّهُمْ أَصْحَابُ الْجَحِيمِ} وَأَنْزَلَ اللَّهُ تَعَالَى فِي أَبِي طَالِبٍ فَقَالَ لِرَسُولِ اللَّهِ ﷺ { إِنَّكَ لاَ تَهْدِي مَنْ أَحْبَبْتَ وَلَكِنَّ اللَّهَ يَهْدِي مَنْ يَشَاءُ وَهُوَ أَعْلَمُ بِالْمُهْتَدِينَ}  

The same hadith is mentioned through a different chain except it ends where it mentions that Allah revealed the verses and it does not mention the verses. There is also a slight variation in words.  

أَنَّ حَدِيثَ صَالِحٍ انْتَهَى عِنْدَ قَوْلِهِ فَأَنْزَلَ اللَّهُ ﷻ فِيهِ وَلَمْ يَذْكُرِ الآيَتَيْنِ وَقَالَ فِي حَدِيثِهِ وَيَعُودَانِ فِي تِلْكَ الْمَقَالَةِ وَفِي حَدِيثِ مَعْمَرٍ مَكَانَ هَذِهِ الْكَلِمَةِ فَلَمْ يَزَالاَ بِهِ  

Make a profession of it that there is no god but Allah and I will bear testimony (of your being a Muslim) on the Day of judgment. But he (Abu Talib) refused to do so. Then Allah revealed this verse: " Verily thou canst not guide to the right path whom thou lovest. And it is Allah Who guideth whom He will and He knoweth best who are the guided" (xxviii. 56).  

قَالَ رَسُولُ اللَّهِ ﷺ لِعَمِّهِ عِنْدَ الْمَوْتِ قُلْ لاَ إِلَهَ إِلاَّ اللَّهُ أَشْهَدُ لَكَ بِهَا يَوْمَ الْقِيَامَةِ فَأَبَى فَأَنْزَلَ اللَّهُ { إِنَّكَ لاَ تَهْدِي مَنْ أَحْبَبْتَ} الآيَةَ  

Make a profession of it that there is no god but Allah and I will bear testimony (of your being a Muslim) on the Day of judgment. He (Abu Talib) said: Were it not the fear of the Quraysh blaming me (and) saying that it was the fear of (approaching death) that induced me to do so, I would have certainly delighted your eyes. It was then that Allah revealed: " Verily thou canst not guide to the right path whom thou lovest. And it is Allah Who guideth whom He will and He knoweth best who are the guided" (xxviii-56).  

قَالَ رَسُولُ اللَّهِ ﷺ لِعَمِّهِ قُلْ لاَ إِلَهَ إِلاَّ اللَّهُ أَشْهَدُ لَكَ بِهَا يَوْمَ الْقِيَامَةِ قَالَ لَوْلاَ أَنْ تُعَيِّرَنِي قُرَيْشٌ يَقُولُونَ إِنَّمَا حَمَلَهُ عَلَى ذَلِكَ الْجَزَعُ لأَقْرَرْتُ بِهَا عَيْنَكَ فَأَنْزَلَ اللَّهُ { إِنَّكَ لاَ تَهْدِي مَنْ أَحْبَبْتَ وَلَكِنَّ اللَّهَ يَهْدِي مَنْ يَشَاءُ}
