Al-Adab Al-Mufrad, Book 42, Hadith 1043 (English) ⓘ
Thabit al-Bannani reported that Anas ibn Malik walked by some children and greeted them. He said, "The Prophet, may Allah bless him and grant him peace, used to do that."
حَدَّثَنَا عَلِيُّ بْنُ الْجَعْدِ، قَالَ: حَدَّثَنَا شُعْبَةُ، عَنْ سَيَّارٍ، عَنْ ثَابِتٍ الْبُنَانِيِّ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّهُ مَرَّ عَلَى صِبْيَانٍ فَسَلَّمَ عَلَيْهِمْ، وَقَالَ: كَانَ النَّبِيُّ صلى الله عليه وسلم يَفْعَلُهُ بِهِمْ.
