Bulugh al-Maram #1540

Anas bin Malik (RAA) narrated, "The Messenger of Allah (ﷺ) used to sacrifice two two-horned rams, mention Allah's name and say the Takbir (Allahu Akbar or Allah is the Most Great), and place his foot on their sides." In another version, "He slaughtered them with his own hands." Another version has, "Two fat rams,' and another has, 'two precious rams.' Agreed upon.
