I have been commanded to recite to you the Sura (al- Bayyinah) which opens with these words (Lam Yakunil-ladhiyna Kafaruu) He said: Has he mentioned to you my name? He said: Yes; thereupon he shed tears of joy.

قَالَ رَسُولُ اللَّهِ ﷺ لأُبَىِّ بْنِ كَعْبٍ إِنَّ اللَّهَ أَمَرَنِي أَنْ أَقْرَأَ عَلَيْكَ { لَمْ يَكُنِ الَّذِينَ كَفَرُوا} قَالَ وَسَمَّانِي قَالَ نَعَمْ قَالَ فَبَكَى
