Tirmidhi

(1) "Slaughter (an animal)" is a command, and furthermore, 'aqiqah is the action of the Prophet (sallallahu alayhi wa sallam), therefore at the very least it is a Sunnah, even though some scholars, due to the imperative form, have declared it obligatory (wajib).

(2) "Remove filth and dirt" refers to the hair of the head. In other words, along with the 'aqiqah, the child's head should also be shaved, and in fact, according to one narration, silver equal to the weight of the hair should be given in charity. Some have interpreted this as referring to circumcision (khitan). Or it may mean that after slaughtering the animal, its blood should not be smeared on the child's head, as was the custom in the Age of Ignorance (Jahiliyyah).

Benefits and Issues:
➊ The animal that is slaughtered on behalf of a newborn is called "Aqiqah."
In the language, its meaning is: to cut and to split.
This word is also used for the hair of every newborn child that grows in the mother's womb, and due to this connection, the sacrifice is called Aqiqah.

➋ The meaning of "shedding blood" is to slaughter an animal.

➌ The meaning of "removing filth" is to shave the head hair.

Benefit:
From this hadith, it is understood that ‘aqiqah is obligatory, and this is the prevalent view. «فأهريقوا» is a command, which indicates obligation. It should be noted that in ‘aqiqah, it is legislated to slaughter two animals on behalf of a boy and one animal on behalf of a girl. The animal should also be a small one, such as a goat (bakra), a young ram (chhatra), or a sheep (dumba).
