“Imam al-Mahdi (a.s.) had sent certain servants to al-Madina of the Messenger of Allah and among them were two servants. He had written to Khafif to leave with them. He then left with them and they reached al-Kufa where one of the two servants had consumed alcohol. Before the would al-Kufa a letter came to them from the army camp (city of Surra man Ra’a) that said, “Send back the servant who has consumed alcohol and remove him from the service.”
