Whenever the Messenger of Allah ﷺ offered a sacrifice, he would buy two fat, horned, white rams. After he had performed the prayer and addressed the people, he would have one of them brought to him while he was standing at his place of prayer, and he would slaughter it himself with the knife.Then he would say, "O Allah, this is on behalf of my entire community, all those who bear witness to Your oneness and bear witness that I have delivered the message."Then the other would be brought, and he would slaughter it himself, saying, "This is on behalf of Muhammad and the family of Muhammad."He would feed both of them to the poor and eat from them along with his family. We remained for years during which no man from Banu Hashim offered a sacrifice, since Allah had spared them the expense and burden through the Messenger of Allah ﷺ.
حدثنا أبو عامر قال حدثنا زهير عن عبد الله بن محمد عن علي بن حسين
أن رسول الله ﷺ كان إذا ضحى اشترى كبشين سمينين أقرنين أملحين فإذا صلى وخطب الناس أتى بأحدهما وهو قائم في مصلاه فذبحه بنفسه بالمدية ثم يقول اللهم إن هذا عن أمتي جميعا ممن شهد لك بالتوحيد وشهد لي بالبلاغ ثم يؤتى بالآخر فيذبحه بنفسه ويقول هذا عن محمد وآل محمد فيطعمهما جميعا المساكين ويأكل هو وأهله منهما فمكثنا سنين ليس رجل من بني هاشم يضحي قد كفاه الله المؤنة برسول الله ﷺ والغرم
