Hadith 8:921
Abu Bakr narrated to us, he said: Yahya bin Sa’id narrated to us, from Ibn Jurayj, from Ibn Sabit, that the Prophet (may Allah bless him and grant him peace) and his companions used to tie the left foreleg of the sacrificial camel and slaughter it while it was standing on its remaining legs.
حدثنا أبو بكر قال حدثنا يحيى بن سعيد عن بن جريج عن بن سابط ان النبي صلى الله عليه وسلم وأصحابه كانوا يعقلون يد البدنة اليسرى وينحرونها قائمة على ما بقي من قوائمها
