حَدَّثَنَا آدَمُ بْنُ أَبِي إِيَاسٍ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنَا قَتَادَةُ، عَنْ أَنَسٍ، قَالَ ضَحَّى النَّبِيُّ صلى الله عليه وسلم بِكَبْشَيْنِ أَمْلَحَيْنِ، فَرَأَيْتُهُ وَاضِعًا قَدَمَهُ عَلَى صِفَاحِهِمَا يُسَمِّي وَيُكَبِّرُ، فَذَبَحَهُمَا بِيَدِهِ‏.‏

Narrated Anas:The Prophet (ﷺ) slaughtered two rams, black and white in color (as sacrifices), and I saw him putting his foot on their sides and mentioning Allah's Name and Takbir (Allahu Akbar). Then he slaughtered them with his own hands
