"A man came to the Prophet ﷺ when he was on the Minbar and said: 'O Messenger of Allah, do you think that if I wield this sword of mine in the cause of Allah, with patience and seeking reward, facing the enemy, and not running away, will Allah forgive my sins?' He said: 'Yes.' When he turned away, he called him back and said: 'Jibril says: unless you are in debt.'" (Using translation from Nasāʾī 3158)
جَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ وَهُوَ عَلَى الْمِنْبَرِ فَقَالَ يَا رَسُولَ اللهِ أَرَأَيْتَ إِنْ ضُرِبْتُ بِسَيْفِي هَذَا فِي سَبِيلِ اللهِ صَابِرًا مُحْتَسِبًا مُقْبِلًا غَيْرَ مُدْبِرٍ حَتَّى أُقْتَلَ أَتُكَفَّرُ عَنِّي خَطَايَايَ؟ قَالَ «نَعَمْ» فَلَمَّا أَدْبَرَ دَعَاهُ فَقَالَ هَذَا جِبْرِيلُ يَقُولُ إِلَّا أَنْ يَكُونَ عَلَيْكَ دَيْنٌ
