حَدَّثَنَا زَكَرِيَّاءُ بْنُ يَحْيَى بْنِ صَالِحٍ الْمِصْرِيُّ، حَدَّثَنَا الْمُفَضَّلُ، - يَعْنِي ابْنَ فَضَالَةَ - عَنْ عَيَّاشٍ، - وَهُوَ ابْنُ عَبَّاسٍ الْقِتْبَانِيُّ - عَنْ عَبْدِ اللَّهِ بْنِ يَزِيدَ أَبِي عَبْدِ الرَّحْمَنِ الْحُبُلِيِّ، عَنْ عَبْدِ اللَّهِ بْنِ عَمْرِو بْنِ الْعَاصِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " يُغْفَرُ لِلشَّهِيدِ كُلُّ ذَنْبٍ إِلاَّ الدَّيْنَ " .
It has been reported on the authority of 'Amr b. al-'As that the Messenger of Allah (ﷺ) said: All the sins of a Shahid (martyr) are forgiven except debt.
