On which day the aqiqah is slaughtered

Sayyiduna Samurah (may Allah be pleased with him) narrates from the Prophet (peace and blessings be upon him) that he (peace and blessings be upon him) said: "On the seventh day (the aqiqah) is to be slaughtered on the child's behalf, his head is to be shaved, and he is to be named."

It is narrated from Amr bin Shu'ayb that the Messenger of Allah (peace and blessings be upon him) ordered, for a newborn, the aqiqah on the seventh day, the cleaning of the head, and the naming of the child.

Mu'tamir bin Sulayman narrates from his father about Ibn Sirin that he saw no harm in performing the aqiqah before or after the seventh day, and he used to say: Do with the aqiqah meat however you wish.

It is narrated from al-Hasan that he said: In the aqiqah there is one grown (musinnah) goat, which is slaughtered on the child's behalf on the seventh day, and the child's head is shaved and he is named.

It is narrated from Abu Ja'far that he said: Sayyidah Fatimah (may Allah be pleased with her) used to perform the aqiqah for her children on the seventh day, and she would name the child, have him circumcised, shave his head, and give in charity the weight of his (hair) in silver.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that he said concerning the aqiqah: It is to be slaughtered on the child's behalf on the seventh day, the child's head is to be shaved, the weight of his hair in silver is to be given in charity, and his head is to be smeared with the blood.
