Asid bin Abu Usaid reported:
A woman who had taken a pledge of allegiance at the hand of the Messenger of Allah (ﷺ) said: "Among the matters in respect of which we gave the Messenger of Allah (ﷺ) the pledge not to disobey him in any Ma'ruf [i.e., all that Islam ordains (V:60:12)] was that we should not slap our faces, bewail, tear our clothes up and tear out our hair (in grief)."[Abu Dawud].
