Sahih al-Bukhari, Hadith 3809 ⓘ
Narrated Anas bin Malik: The Prophet said to Ubai, "Allah has ordered me to recite to you: 'Those who disbelieve (Surat-al- Bayina 98).' " Ubai said, "Has He mentioned my name?" The Prophet said, "Yes." On hearing this, Ubai started weeping.
حَدَّثَنِي مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا غُنْدَرٌ، قَالَ سَمِعْتُ شُعْبَةَ، سَمِعْتُ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ النَّبِيُّ صلى الله عليه وسلم لأُبَىٍّ " إِنَّ اللَّهَ أَمَرَنِي أَنْ أَقْرَأَ عَلَيْكَ {لَمْ يَكُنِ الَّذِينَ كَفَرُوا} ". قَالَ وَسَمَّانِي قَالَ " نَعَمْ " فَبَكَى.
