سنن النسائي

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.'"
