Narrator:Abu Qatāda
وَعَن أبي قَتَادَة قَالَ: قَالَ رَجُلٌ: يَا رَسُولَ اللَّهِ أَرَأَيْتَ إِنْ قُتِلْتُ فِي سَبِيلِ اللَّهِ صَابِرًا مُحْتَسِبًا مُقبلا غير مُدبر يكفر اللَّهُ عَنِّي خَطَايَايَ؟ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «نَعَمْ» . فَلَمَّا أَدْبَرَ نَادَاهُ فَقَالَ: «نَعَمْ إِلَّا الدَّيْنَ كَذَلِكَ قَالَ جِبْرِيلُ» . رَوَاهُ مُسْلِمٌ
Abu Qatada told of a man saying, “Tell me, Messenger of God, if I am killed in God’s path showing endurance, seeking my reward from God, advancing and not retreating, will God efface my sins?” He replied, “Yes,” but when the man turned away he called him and said, “Yes, with the exception of a debt. Thus Gabriel said.” Muslim transmitted it.
