Al-Adab Al-Mufrad, Book 53, Hadith 1246 (In-Book) ⓘ
Salim said, "Ibn 'Umar, Nu'aym and I were circumcised and they sacrificed a ram on our behalf. I think that we were more happy about it than the other children since a ram had been sacrificed on our behalf."
حَدَّثَنَا زَكَرِيَّا بْنُ يَحْيَى، قَالَ: حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ عُمَرَ بْنِ حَمْزَةَ قَالَ: أَخْبَرَنِي سَالِمٌ قَالَ: خَتَنَنِي ابْنُ عُمَرَ أَنَا وَنُعَيْمًا، فَذَبَحَ عَلَيْنَا كَبْشًا، فَلَقَدْ رَأَيْتُنَا وَإِنَّا لَنَجْذَلُ بِهِ عَلَى الصِّبْيَانِ أَنْ ذَبَحَ عَنَّا كَبْشًا.
