Tradition

Habeera narrates that Imam Hasan b. Ali (a.s.) came (after the martyrdom of Ameerul Momineen (a.s.)) while he was wearing a black turban and said – yesterday, there was a man amongst you whom none could exceed in the past nor anyone would reach him in future. No doubt the Prophet (s.a.w.a.) had said (on the Day of Khyber) – I will give the flag to the one who loves Allah and his Prophet and is beloved of Allah and his Prophet; and he would fight with Jibrail on his right side, and Mikail on his left side; and he will not return till Allah grants him victory and he did not leave anything but 7 dirham, with which he intended to get a servant for his family.
