Muhammad b. ‘All b. Husain quoted ‘Ali b. Abu Talib as saying that God’s messenger sacrificed a sheep on the seventh day for al-Hasan and said, “Shave his head, Fatima, and give the weight of his hair in silver as sadaqa.” So they weighed it and it amounted to a dirham or part of a dirham.
Tirmidhi transmitted it, saying this is a hasan gharib tradition, but its isnad is not fully connected because Muhammad b. ‘Ali b. Husain was not born in the time of ‘Ali b. Abu Talib.
'Amr b. Shu'aib, on his father's authority, said his grandfather told that God’s messenger was asked about the ‘aqiqa and replied, “God does not like the breaking of ties (‘uquq),” as though he disliked the name. And he said, “If anyone has a child born to him and wishes to offer a sacrifice on its behalf, he may offer two sheep for a boy and one for a girl.
Al-Hasan quoted Samura who reported God’s messenger as saying, "A boy is in pledge for his ‘aqiqa. Sacrifice is made for him on the seventh day, he is given a name and his head is shaved.”
Ahmad, Tirmidhi, Abu Dawud and Nasa’i transmitted it, but the last two have “a pledge” for “in pledge.” A version by Ahmad and Abu Dawud has “is smeared with blood” 1 in place of “is given a name.” Abu Dawud says th at “is given a name” is sounder.
