He said (to me): Umm Ma'qil, what prevented you from coming out for hajj along with us?
She said: We resolved (to do so), but Abu Ma'qil died. We had a camel on which we could perform hajj, but Abu Ma'qil had bequeathed it to the cause of Allah.
He said: Why did you not go out (for hajj) upon it, for hajj is in the cause of Allah? If you miss this hajj along with us, perform umrah during Ramadan, for it is like hajj.
She used to say: hajj is hajj, and umrah is umrah. The Messenger of Allah (ﷺ) said it to me: I do not know whether it was peculiar to me.
