It was narrated that Anas bin Malik said: “I saw the Messenger of Allah slaughter his sacrifice with his own hand, placing his foot on its side.”
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، سَمِعْتُ قَتَادَةَ، يُحَدِّثُ عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ لَقَدْ رَأَيْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ يَذْبَحُ أُضْحِيَّتَهُ بِيَدِهِ وَاضِعًا قَدَمَهُ عَلَى صِفَاحِهَا .
