Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) sacrificed two rams with black eyes and horns. He (peace be upon him) took the name of Allah and said Takbeer. I saw that he (peace be upon him) slaughtered them with his blessed hand, and he (peace be upon him) had placed his blessed foot on their side.
