Self-flagellation
إِخْوَانِي الذَّاهِبُونَ فَحَقَ لَنَا أَنْ نَظْمَأَ إِلَيْهِمْ وَ نَعَضَّ الْأَيْدِي عَلَى فِرَاقِهِمْ
Amir ul-Momineen–asws say in Nahjul Balagha: These are my–asws comrades who have departed. We should be justified if we feel eager for them and bite our hands in their separation. (This is for just comrades, what should be our grief on the martyrdom of Ahl Al-Bayt–asws?)[1]
