Verily Allah, the Exalted and Glorious, has commanded me to recite the Qur'an to you, whereupon he said: (Has) Allah mentioned my name to you? He said: Allah has mentioned your name to me. Thereupon he began to shed tears (of joy)
حَدَّثَنَا هَدَّابُ بْنُ خَالِدٍ، حَدَّثَنَا هَمَّامٌ، حَدَّثَنَا قَتَادَةُ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ لأُبَىٍّ ‏
"‏ إِنَّ اللَّهَ عَزَّ وَجَلَّ أَمَرَنِي أَنْ أَقْرَأَ عَلَيْكَ ‏"‏ ‏.‏ قَالَ آللَّهُ سَمَّانِي لَكَ قَالَ ‏"‏ اللَّهُ سَمَّاكَ لِي ‏"‏ ‏.‏ قَالَ فَجَعَلَ أُبَىٌّ يَبْكِي ‏.‏
