I asked Abā ‘Abdillāh (Imam Sādiq (a.s.)) on the route from Madīnah to Makkah, “O son of the Messenger of Allāh! Why do I see you so depressed, saddened, and grieved?” Imam (a.s.) replied, “If you could hear that which I hear, you would have been distracted from asking me this question.” I asked, “What do you hear?” Imam (a.s.) replied: (I hear the voice of) the angels beseeching Allāh, the Great and Almighty, to curse the killers of the Commander of the Believers and the killers of Ḥusain (a.s.). And (I hear the voice of) lamentation of the Jinn and the intense restlessness and weeping of the angels who are around him (Imam Ḥusain (a.s.)). So who can enjoy food, drink, or sleeping after hearing these voices?!
