عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ لِعَمِّهِ قُلْ لَا إِلَهَ إِلَّا اللَّهُ أَشْهَدُكَ بِهَا يَوْمَ الْقِيَامَةِ قَالَ لَوْلَا أَنْ تُعَيِّرَنِي قُرَيْشٌ يَقُولُونَ إِنَّمَا حَمَلَهُ عَلَى ذَلِكَ الْجَزَعُ لَأَقْرَرْتُ بِهَا عَيْنَكَ فَأَنْزَلَ اللَّهُ عَزَّ وَجَلَّ {إِنَّكَ لَا تَهْدِي مَنْ أَحْبَبْتَ} [القصص: 56] الآية
Syedna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him and his family) said to his uncle: Say "There is no god but Allah," and I will testify on your behalf because of it on the Day of Resurrection. He replied: If it were not that the Quraysh would reproach me by saying that weakness has led Abu Talib to utter this word, I would say this word and bring coolness to your eyes. Then Allah Almighty revealed: Surely, you do not guide whom you love.
