Sunan an-Nasa'i, Hadith 4379 ⓘ
It was narrated from 'Uqbah bin 'Amair that: the Messenger of Allah gave him some sheep to distribute among his Companions. A small goat was left over and he mentioned that to the Messenger of Allah. He said: "Sacrifice it yourself."
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ يَزِيدَ بْنِ أَبِي حَبِيبٍ، عَنْ أَبِي الْخَيْرِ، عَنْ عُقْبَةَ بْنِ عَامِرٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم أَعْطَاهُ غَنَمًا يُقَسِّمُهَا عَلَى صَحَابَتِهِ فَبَقِيَ عَتُودٌ فَذَكَرَهُ لِرَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَ " ضَحِّ بِهِ أَنْتَ " .
