What qualifies as a sacrifice
حَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ، أَنْبَأَنَا اللَّيْثُ بْنُ سَعْدٍ، عَنْ يَزِيدَ بْنِ أَبِي حَبِيبٍ، عَنْ أَبِي الْخَيْرِ، عَنْ عُقْبَةَ بْنِ عَامِرٍ الْجُهَنِيِّ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ أَعْطَاهُ غَنَمًا فَقَسَمَهَا عَلَى أَصْحَابِهِ ضَحَايَا فَبَقِيَ عَتُودٌ فَذَكَرَهُ لِرَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ فَقَالَ " ضَحِّ بِهِ أَنْتَ " .
It was narrated from ‘Uqbah bin ‘Amir Al-Juhani that the Messenger of Allah (ﷺ) gave him some sheep, and he distributed them among his Companions to be sacrificed. There remained an ‘Atud.* He mentioned that to the Messenger of Allah (ﷺ) and he said: “You sacrifice it yourself.”
