Yahya bin Sa'id al-Ansari يحيى بن سعيد الأنصاري · Chapters on Sacrifices

“The Messenger of Allah (ﷺ) used to sacrifice two horned, black-and-white rams and he would say the Name of Allah and pronounce His greatness. I saw him slaughtering them with his own hand, putting his foot on their sides.”

It was narrated from Qatadah that he said that he heard Juray bin Kulaib narrate that he heard ‘Ali narrate that the Messenger of Allah (ﷺ) forbade sacrificing animals with broken horns and ears.
