حَدَّثَنَا هُشَيْمٌ أَخْبَرَنَا يُونُسُ أَخْبَرَنِي زِيَادُ بْنُ جُبَيْرٍ قَالَ كُنْتُ مَعَ ابْنِ عُمَرَ بِمِنًى فَمَرَّ بِرَجُلٍ وَهُوَ يَنْحَرُ بَدَنَةً وَهِيَ بَارِكَةٌ فَقَالَ ابْعَثْهَا قِيَامًا مُقَيَّدَةً سُنَّةَ مُحَمَّدٍ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ
مسند امام احمد بن حنبل · Hadith 4459
It was narrated that Ziyaad ibn Jubayr said: I was with Ibn 'Umar in Mina. He passed by a man who was slaughtering his sacrificial camel as it was sitting. He said: Make it stand up and tie it, the Sunnah of Muhammad (PBUH).
