Sunan an-Nasa'i

It was narrated that Abu Hurairah said: "A man came to the Prophet (ﷺ) while he was delivering a Khutbah from the Minbar, and he said: “If I fight in the cause of Allah with patience and seeking reward, facing the enemy and not running away, do you think that Allah will forgive my sins?' He said: “Yes.' Then he fell silent for a while. Then he said: “Where is the one who was asking just now?' The man said: “Here I am.' He said: “What did you say?' He said: “What did you say?' He said: “I said: I said: If I fight in the cause of Allah with patience and seeking reward,facing the enemy and not running away, do you think that Allah will forgive my sins?' He said: “Yes, except for debt. Jibril told me that just now””””””””"
