The Messenger of Allah ﷺ ordered that a horned ram be brought, one that walked among black, rested among black, and looked through black. It was brought to him so he could sacrifice it.He said to her, "Ayesha, bring the knife."Then he said, "Sharpen it on a stone."She did so, then he took it, took hold of the ram, laid it on its side, and slaughtered it, saying, "In the name of Allah. O Allah, accept this from Muhammad, the family of Muhammad, and the nation of Muhammad."Then he sacrificed it.
أن رسول الله ﷺ أمر بكبش أقرن، يطأ في سواد ويبرك في سواد، وينظر في سواد فأتي به ليضحي به فقال لها: يا عائشة هلمي المدية ثم قال: الحديها بحجر ففعلت ثم أخذها وأخذ الكبش فأضجعه، ثم ذبحه ثم قال: باسم الله، اللهم تقبل من محمد وآل محمد، ومن أمة محمد، ثم ضحى به.
Muslim narrated it in the chapter on sacrifices (19:1967), from Harun bin Maruf, who said, Abdullah bin Wahb narrated to us, he said, Haywa said, Abu Sakhr informed me, from Yazid bin Qusayt, from Urwa bin Zubayr, from Ayesha, and he mentioned it.His saying, "Sharpen it," means, make it sharp.
