Answer
Nabi (Sallallaahu Alayhi Wasallam) has prohibited us from cutting and mutilating the human body. Nevertheless, the object of Dhikr is not to get into such a condition where you begin to do unnatural things, but it is a means of gaining proximity of Allah Ta’ala and earning his mercy.
and Allah Ta’ala Knows Best
