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 فَقَالَابْعَثْهَا قِيَامًا مُقَيَّدَةً سُنَّةَ مُحَمَّدٍ صلى الله عليه وسلم ‏.‏

Ziyad bin Jubair said

Ahmad ibn Hanbal told us: Hushaym told us: Yunus informed us: Ziyad ibn Jubayr informed me, saying: I was with Ibn Umar in Mina when he passed by a man who was slaughtering his sacrificial camel while it was kneeling down. He said: "Make it stand up, tied by its leg, following the Sunnah of Muhammad, may Allah bless him and grant him peace."
