أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا إِسْمَاعِيلُ، عَنْ عَبْدِ الْعَزِيزِ، - وَهُوَ ابْنُ صُهَيْبٍ - عَنْ أَنَسٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ يُضَحِّي بِكَبْشَيْنِ ‏.‏ قَالَ أَنَسٌ وَأَنَا أُضَحِّي بِكَبْشَيْنِ ‏.‏

It was narrated that Anas said

"The Prophet sacrificed two horned, Amlah rams, slaughtering them with his own hand, pronouncing the name of Allah, and saying: 'Allahu Akbar, and placing his foot on their sides."
