Narrated to me Abul Hasan Musawi Khyberi: My father narrated that he was with Imam Hasan Askari (a.s) during many nights in Samarrah: One day a mount was brought for the Imam (a.s) to take him to the ruler. Imam (a.s) was furious at this. A Sunni man came to take the Imam and when the Imam was mounted, he also mounted his beast in a disrespectful manner. He harassed the Imam (a.s) and the latter was much disturbed by this. That day the Sunni man was more audacious to the Imam and spoke to him in a very harsh fashion. They rode on till they came to a fork on the road. Since the road was narrow and many quadrupeds were crossing it, it was not possible for two riders to ride abreast of each other. So he left the road to rejoin the Imam from a shortcut. During this period Imam (a.s) called to one of his servants: Go and shroud this man. The servant obeyed the Imam. When Imam (a.s) reached the market and we were also accompanying the Imam, that man entered the road to apprehend the Imam and to harass him through abuses and insult. At the place he entered, road stood a mule, which killed him with a single kick. The Imam’s servant shrouded him as the Imam had ordered and the Imam continued on his journey and we followed.
