Sahih Muslim Book - 1, Hadith - 132

و حَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى التُّجِيبِيُّ أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ قَالَ أَخْبَرَنِي يُونُسُ عَنْ ابْنِ شِهَابٍ قَالَ أَخْبَرَنِي سَعِيدُ بْنُ الْمُسَيَّبِ عَنْ أَبِيهِ قَالَ لَمَّا حَضَرَتْ أَبَا طَالِبٍ الْوَفَاةُ جَاءَهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَوَجَدَ عِنْدَهُ أَبَا جَهْلٍ وَعَبْدَ اللَّهِ بْنَ أَبِي أُمَيَّةَ بْنِ الْمُغِيرَةِ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَا عَمِّ قُلْ لَا إِلَهَ إِلَّا 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 صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَعْرِضُهَا عَلَيْهِ وَيُعِيدُ لَهُ تِلْكَ الْمَقَالَةَ حَتَّى قَالَ أَبُو طَالِبٍ آخِرَ مَا كَلَّمَهُمْ هُوَ عَلَى مِلَّةِ عَبْدِ الْمُطَّلِبِ وَأَبَى أَنْ يَقُولَ لَا إِلَهَ إِلَّا اللَّهُ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَمَا وَاللَّهِ لَأَسْتَغْفِرَنَّ لَكَ مَا لَمْ أُنْهَ عَنْكَ فَأَنْزَلَ اللَّهُ تَبَارَكَ وَ تَعَالَى { مَا كَانَ لِلنَّبِيِّ وَالَّذِينَ آمَنُوا أَنْ يَسْتَغْفِرُوا لِلْمُشْرِكِينَ وَلَوْ كَانُوا أُولِيْ قُرْبَى مِنْ بَعْدِ مَا تَبَيَّنَ لَهُمْ أَنَّهُمْ أَصْحَابُ الْجَحِيمِ } وَأَنْزَلَ اللَّهُ تَعَالَى فِي أَبِي طَالِبٍ فَقَالَ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ { إِنَّكَ لَا تَهْدِي مَنْ أَحْبَبْتَ وَلَكِنَّ اللَّهَ يَهْدِي مَنْ يَشَاءُ وَهُوَ أَعْلَمُ بِالْمُهْتَدِينَ }[القصص:56]

Sa'eed bin Al-Musayyab narrated that his father said: "When Abu Talib was dying, the Messenger of Allah (s.a.w) came to him and found Abu Jahl and 'Abdullah bin Abi Umayyah bin Al-Mughirah with him. The Messenger of Allah (s.a.w) said: 'O uncle, say La ilaha illallah, a word for which I will testify for you before Allah.' Abu Jahl and 'Abdullah bin Abi Umayyah said: 'O Abu Talib, will you tum away from the religion of 'Abdul-Muttalib?' The Messenger of Allah (s.a.w) kept calling him to Islam and he repeated this statement to him, until the last words that Abu Talib spoke indicated that he followed the religion of 'Abdul-Muttalib, and he refused to say La ilaha illallah. The Messenger of Allah (s.a.w) said: 'By Allah, I shall pray for forgiveness for you so long as I am not forbidden to do so.' Then Allah, Most High revealed: "It is not (proper) for the Prophet and those who believe to ask Allah's forgiveness for the Mushrikun even though they be of kin, after it has become clear to them that they are the dwellers of the Fire. And Allah, Most High revealed concerning Abu Talib, and said to the Messenger of Allah (s.a.w): "Verily, you (O Muhammad) guide not whom you like, but Allah guides whom He wills. And He knows best those who are the guided.''
