Al-Mutawakkil was full of rage whenever he heard or saw crowds of people visit the shrine of Imam al-Husayn (a.s.) the master of the youth of Paradise, whereas the graves of his (al-Mutawakkil’s) fathers and their cousins the Umayyads turned into dunghills in dark, dreary places, which became resorts for beasts. Those graves, with their misery and gloominess, spoke of the oppression and violence of their inhabitants against Muslims.

Historians say that the reason, which made al-Mutawakkil destroy the holy shrine, was that some songstress sent him her maids before he assumed the rule to sing for him when he drank, and when he became the caliph, he sent for her to send him a songstress but she was not there. It was said to him that she had gone to visit the holy tomb of Imam al-Husayn (a.s.). She was informed of that while she was in Kerbala. She hurried back to Baghdad and sent al-Mutawakkil one of her maids.
