Musannaf Ibn Abi Shaybah

Hazrat Alqamah narrates that we laid siege to the city of Nahavand, and I gave one of my garments to Hazrat Mu'azzad, and he tied it as a turban. A stone struck his head. He began to rub his head and, looking towards me, said: "This is very small, and Allah Almighty will grant blessing in what is small."
