Narrated Anas said that God’s Messenger sacrificed with his own hand two horned rams which were white with black markings, mentioned God’s name and said, "God is most great.” He added:
I saw him placing his foot on their sides and saying, "In the name of God. God is most great.”
God's Messenger used to go out on the day of sacrifice and the day of the breaking of the fast, first of all pray, and when he had prayed stand up facing the people while they were seated in their place of prayer. If he had cause to send out an expedition he mentioned it to the people, or if he required anything else he gave them commands about it, and he would say, “Give alms, give alms, give alms." Those who gave most were the women. Then he would go away. This practice went on till the time of Marwan b. al-Hakam.* I went out hand in hand with Marwan, and when we came to the place of prayer we saw that Kathir b. as Salt had built a pulpit of clay and brick. Marwan began to tug me with his hand as though he were pulling me towards the pulpit, while I was pulling him towards the prayer. When I saw what he was doing I said, “What has happened to the practice of beginning with prayer?" He replied, “No, Abu Sa'id, what you are familiar with has been abandoned." I thereupon said three times, “By no means, by Him in whose hand my soul is, you are not doing something better than what I am familiar with." Then he went away.
‘A’isha said that God’s Messenger ordered a horned ram with black legs, a black belly and black round the eyes, and it was brought for him to sacrifice. He told ‘A’isha to get the knife, and then told her to sharpen it with a stone. When she had done so he took it, then taking the ram he placed it on the ground and cut its throat. He then said, "In the name of God. O God, accept it from Muhammad, Muhammad’s family and Muhammad’s people.” Then he sacrificed it.
‘Ata’ informed me on the authority of Ibn ‘Abbas and Jabir b. ‘Abdallah that the adhan was not called on the day of the breaking of the fast or on the day of sacrifice. I later asked him, i.e., ‘Ata’, about that, and he told me that Jabir b. ‘Abdallah told him there was no adhan for the prayer on the day of the breaking of the fast when the imam came out or after he came out, no iqama and no summons; there was nothing, no summons or iqama that day.
