Hadith
أَخْبَرَنِي عَمْرُو بْنُ عُثْمَانَ، قَالَ حَدَّثَنَا بَقِيَّةُ، قَالَ حَدَّثَنَا بَحِيرٌ، عَنْ خَالِدٍ، عَنِ ابْنِ أَبِي بِلاَلٍ، عَنِ الْعِرْبَاضِ بْنِ سَارِيَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " يَخْتَصِمُ الشُّهَدَاءُ وَالْمُتَوَفَّوْنَ عَلَى فُرُشِهِمْ إِلَى رَبِّنَا فِي الَّذِينَ يُتَوَفَّوْنَ مِنَ الطَّاعُونِ فَيَقُولُ الشُّهَدَاءُ إِخْوَانُنَا قُتِلُوا كَمَا قُتِلْنَا . وَيَقُولُ الْمُتَوَفَّوْنَ عَلَى فُرُشِهِمْ إِخْوَانُنَا مَاتُوا عَلَى فُرُشِهِمْ كَمَا مُتْنَا فَيَقُولُ رَبُّنَا انْظُرُوا إِلَى جِرَاحِهِمْ فَإِنْ أَشْبَهَ جِرَاحُهُمْ جِرَاحَ الْمَقْتُولِينَ فَإِنَّهُمْ مِنْهُمْ وَمَعَهُمْ فَإِذَا جِرَاحُهُمْ قَدْ أَشْبَهَتْ جِرَاحَهُمْ " .
It was narrated from Al-'Irbad bin Sariyah that the Messenger of Allah (ﷺ) said:"The martyrs and those who dies in their beds referred a dispute to our Lord concerning those who dies of the plague. The martyrs said: 'Our brothers were killed as we were killed.' And those who dies in their beds said: 'Our brothers dies on their beds as we died.' Our Lord said: 'Look at their wounds; if their wounds; if their wounds are like the wounds of those who were killed then they are of them and belong with them.' And their wounds were like their (the martyrs') wounds
