باب اسْتِحْبَابِ الضَّحِيَّةِ وَذَبْحِهَا مُبَاشَرَةً بِلاَ تَوْكِيلٍ وَالتَّسْمِيَةِ وَالتَّكْبِيرِ ‏‏

'A'isha reported that Allah's Messenger (ﷺ) commanded that a ram with black legs, black belly and black (circles) round the eyes should be brought to him, so that he should sacrifice it. He said to 'A'isha:

Give me the large knife, and then said: Sharpen it on a stone. She did that. He then took it (the knife) and then the ram; he placed it on the ground and then sacrificed it, saying: Bismillah, Allah-humma Taqabbal min Muhammadin wa Al-i-Muhammadin, wa min Ummati Muhammadin (In the name of Allah," O Allah, accept [this sacrifice] on behalf of Muhammad and the family of Muhammad and the Umma of Muhammad" ).
حَدَّثَنَا هَارُونُ بْنُ مَعْرُوفٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، قَالَ قَالَ حَيْوَةُ أَخْبَرَنِي أَبُو صَخْرٍ، عَنْ يَزِيدَ بْنِ قُسَيْطٍ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، عَنْ عَائِشَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم 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 اللَّهِ اللَّهُمَّ تَقَبَّلْ مِنْ مُحَمَّدٍ وَآلِ مُحَمَّدٍ وَمِنْ أُمَّةِ مُحَمَّدٍ ‏"‏ ‏.‏ ثُمَّ ضَحَّى بِهِ ‏.‏
