(23) باب مِنْ فَضَائِلِ أُبَىِّ بْنِ كَعْبٍ وَجَمَاعَةٍ مِنَ الأَنْصَارِ رَضِيَ اللَّهُ تَعَالَى عَنْهُمْ .
Anas b. Malik reported that Allah's Messenger (ﷺ) said to Ubayy:
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)
