Narrated Anas bin Malik:
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 لِأُبَيٍّ " إِنَّ اللَّهَ أَمَرَنِي أَنْ أَقْرَأَ عَلَيْكَ {لَمْ يَكُنِ الَّذِينَ كَفَرُوا} ". قَالَ وَسَمَّانِي قَالَ " نَعَمْ " فَبَكَى.
The Prophet (ﷺ) 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 (ﷺ) said, "Yes." On hearing this, Ubai started weeping.
