1. It is established from the Sunnah that the head of the child is to be shaved on the seventh day after the birth:
From Samurah (radiyallaahu `anhu) that Allaah’s Messenger (salallaahu `alaihi wassallaam) said:
“A child is held in pledge by his `aqeeqah that is slaughtered on his behalf on the seventh day, and he is named and his head is shaved.”
Reported by Ahmad (7/5), Abu Dawood (2838), At-Tirmidhee (1522). It was graded Saheeh by: At-Tirmidhee, Al-Haakim, Abdur-Razzaaq Al-Ishbeelee and others.
Salmaan Ibn `Aamir Ad-Dabbee (radiyallaahu ‘anhu) said that: I heard Allaah’s Messenger (salallaahu `alaihi wassallam) say:
“For the child there is an `aqeeqah, so spill blood on his behalf (i.e. slaughter an animal) and remove from him harm.”
Al-Bukhaaree (5472), Abu Dawood (2839).
Al-Hasan Al-Basree (d. 110H, rahimahullaah) said:
“The removal of harm is shaving the head.”
Reported by Abu Dawood (2840).
Ibn Abdil-Barr said in At-Tamheed (4/318) said:
“As for the shaving of the head of the child at the time of `aqeeqah, then the scholars used to recommend that – and it is established from the Prophet (salallaahu `alaihi wassallam) in the hadeeth regarding the `aqeeqah, ‘His head is shaved and he is named.’”
