Sahih al-Bukhari · Book 25: Hajj (Pilgrimage) · Slaughtering the camels after tying their one leg
Narrated Ziyad bin Jubair:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ ، عَنْ يُونُسَ ، عَنِ زِيَادِ بْنِ جُبَيْرٍ ، قَالَ رَأَيْتُ ابْنَ عُمَرَ ـ رضى الله عنهما ـ أَتَى عَلَى رَجُلٍ، قَدْ أَنَاخَ بَدَنَتَهُ يَنْحَرُهَا، قَالَ ابْعَثْهَا قِيَامًا مُقَيَّدَةً، سُنَّةَ مُحَمَّدٍ صلى الله عليه وسلم. وَقَالَ شُعْبَةُ عَنْ يُونُسَ أَخْبَرَنِي زِيَادٌ .
I saw Ibn `Umar passing by a man who had made his Badana sit to slaughter it. Ibn `Umar said, "Slaughter it while it is standing with one leg tied up as is the tradition of Muhammad."
