Samurah (RAA) narrated that Allah's Messenger (ﷺ) said:
"Every boy is pawned against his 'Aqiqah, to be slaughtered on his behalf on the seventh day of his birth, his head is to be shaved, and he must be given a name." Related by the five Imams (Ahmad and the four Imams). At-Tirmidhi graded it as Sahih.
