Yahya related to me from Malik that Yahya ibn Said said, "TheMessenger of Allah, may Allah bless him and grant him peace, wassitting by a grave which was being dug at Madina. A man looked intothe grave and said, 'An awful bed for the mumin. 'The Messenger ofAllah, may Allah blesshim and grant him peace, said, 'Evil? What youhave said is absolutely wrong.'The man said, 'I didn't meanthat, Messenger of Allah. I meant being killed in the way of Allah.'The Messenger of Allah, may Allah bless him and grant him peace, said,'Being killed in the way of Allah has no like! There is no place onthe earth which I would prefer my grave to be than here (meaningMadina). He repeated it three times.' "
