One of the oaths which the Messenger of Allah ﷺ received from us about the virtue was that we would not disobey him in it (virtue): that we would not scratch the face, nor wail, nor tear the front of the garments nor dishevel the hair.
كَانَ فِيمَا أَخَذَ عَلَيْنَا رَسُولُ اللَّهِ ﷺ فِي الْمَعْرُوفِ الَّذِي أَخَذَ عَلَيْنَا أَنْ لاَ نَعْصِيَهُ فِيهِ أَنْ لاَ نَخْمِشَ وَجْهًا وَلاَ نَدْعُوَ وَيْلاً وَلاَ نَشُقَّ جَيْبًا وَأَنْ لاَ نَنْشُرَ شَعْرًا
