حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا هُشَيْمٌ، أَخْبَرَنَا يُونُسُ، أَخْبَرَنِي زِيَادُ بْنُ جُبَيْرٍ، قَالَ كُنْتُ مَعَ ابْنِ عُمَرَ بِمِنًى فَمَرَّ بِرَجُلٍ وَهُوَ يَنْحَرُ بَدَنَتَهُ وَهِيَ بَارِكَةٌ فَقَالَ ابْعَثْهَا قِيَامًا مُقَيَّدَةً سُنَّةَ مُحَمَّدٍ صلى الله عليه وسلم ‏.‏

Ziyad bin Jubair said :I was present with Ibn `Umar at Minah. He passed a man who was sacrificing his camel while it was sitting. He said make it stand and tie its leg ; thus follow the practice (sunnah) of Muhammad (SWAS)
