Amir al-Sha'bi عامر الشعبي · The Book of ad-Dahaya (Sacrifices)

"I heard my father narrating from a man who said: 'We were with the Messenger of Allah two days before Al-Adha and we started to offer two Jadh ahs for one Thaniiyah, Then the Messenger of Allah said: 'A Jadh'ah is sufficient for that for which a Thaniyah is sufficient."

the Messenger of Allah used to sacrifice two rams. And Anas said: "And I sacrifice two rams."

"Then he" meaning the Prophet on the Day of Sacrifice - "Went toward two Amlah rams and sacrificed them, then (he went toward) a small flock of sheep and distributed them among us." (Sahih )

"Do not take anything that has a soul as a target."
