Praise be to Allah.;
In Islamic shari’ah, hair is divided into 3 types:
First: Hair that has been ordered to remain, such as man’s beard.
Second: Hair that has been ordered to be removed, such as pubic hair, the hair of the armpits, and the extension of the mustache if it reached the lips.
Third: Hair about which we are told nothing, such as hair of hands, legs, chest, and back; this hair is permissible to be removed and Allah is the most Knowledgeable.
