Qais bin Sa’d narrates: I said to my father: I was present in that army which was called the Army of Leaves. People were afflicted with hunger, so my father said to me: You should sacrifice. I replied: I will sacrifice. Then people faced severe hunger, so my father said to me: You should sacrifice! I replied: I will sacrifice. Then people faced hunger again, so my father said to me: You should sacrifice, so I replied: I have been forbidden from this (by the commander of the army).
