Narrated Sahl bin Bakkar:
حَدَّثَنَا سَهْلُ بْنُ بَكَّارٍ ، حَدَّثَنَا وُهَيْبٌ ، عَنْ أَيُّوبَ ، عَنْ أَبِي قِلاَبَةَ ، عَنْ أَنَسٍ ـ وَذَكَرَ الْحَدِيثَ ـ قَالَ وَنَحَرَ النَّبِيُّ صلى الله عليه وسلم بِيَدِهِ سَبْعَ بُدْنٍ قِيَامًا، وَضَحَّى بِالْمَدِينَةِ كَبْشَيْنِ أَمْلَحَيْنِ أَقْرَنَيْنِ. مُخْتَصَرًا.
The narration of Anas abridged, saying, "The Prophet (ﷺ) slaughtered seven Budn (camels) while standing, with his own hands. On the day of `Id-ul-Adha he slaughtered (sacrificed) two horned rams, black and white in color.
