Sahih Muslim Book - 35, Hadith - 5091

حَدَّثَنَا هَارُونُ بْنُ مَعْرُوفٍ ، حَدَّثَنَا عَبْدُ اللهِ بْنُ وَهْبٍ ، قَالَ: قَالَ حَيْوَةُ: أَخْبَرَنِي أَبُو صَخْرٍ ، عَنْ يَزِيدَ بْنِ قُسَيْطٍ ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ ، عَنْ عَائِشَةَ ، أَنَّ رَسُولَ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَمَرَ بِكَبْشٍ أَقْرَنَ يَطَأُ فِي سَوَادٍ ، وَيَبْرُكُ فِي سَوَادٍ ، وَيَنْظُرُ فِي سَوَادٍ ، فَأُتِيَ بِهِ لِيُضَحِّيَ بِهِ ، فَقَالَ لَهَا: يَا عَائِشَةُ ، هَلُمِّي الْمُدْيَةَ ، ثُمَّ قَالَ: اشْحَذِيهَا بِحَجَرٍ ، فَفَعَلَتْ: ثُمَّ أَخَذَهَا ، وَأَخَذَ الْكَبْشَ فَأَضْجَعَهُ ، ثُمَّ ذَبَحَهُ ، ثُمَّ قَالَ: بِاسْمِ اللهِ ، اللَّهُمَّ تَقَبَّلْ مِنْ مُحَمَّدٍ ، وَآلِ مُحَمَّدٍ ، وَمِنْ أُمَّةِ مُحَمَّدٍ ، ثُمَّ ضَحَّى بِهِ.

It was narrated from 'Aishah that the Messenger of Allah (s.a.w) ordered that a horned ram, with black legs, a black belly and black around its eyes, be brought for him to sacrifice it. He said to 'Aishah: "Bring me the knife." Then he said: "Sharpen it on a stone." She did that, then he took it and he took the ram and made it lie down, then he slaughtered it and said: "In the Name of Allah, O Allah, accept it from Muhammad and the family of Muhammad and from the Ummah of Muhammad." Then he sacrificed it.
