Ways to be martyred
Abu Hurairah
حَدَّثَنَا أَبُو عَاصِمٍ، عَنْ مَالِكٍ، عَنْ سُمَىٍّ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم " الشُّهَدَاءُ الْغَرِقُ وَالْمَطْعُونُ وَالْمَبْطُونُ وَالْهَدْمُ ". وَقَالَ " وَلَوْ يَعْلَمُونَ مَا فِي التَّهْجِيرِ لاَسْتَبَقُوا {إِلَيْهِ} وَلَوْ يَعْلَمُونَ مَا فِي الْعَتَمَةِ وَالصُّبْحِ لأَتَوْهُمَا وَلَوْ حَبْوًا، وَلَوْ يَعْلَمُونَ مَا فِي الصَّفِّ الْمُقَدَّمِ لاَسْتَهَمُوا ".
Narrated Abu Huraira: The Prophet (ﷺ) said, "Martyrs are those who die because of drowning, plague, an Abdominal disease, or of being buried alive by a falling building." And then he added, "If the people knew the Reward for the Zuhr prayer in its early time, they would race for it. If they knew the reward for the’Isha' and the Fajr prayers in congregation, they would join them even if they had to crawl. If they knew the reward for the first row, they would draw lots for it."

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ سُمَىٍّ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " بَيْنَمَا رَجُلٌ يَمْشِي بِطَرِيقٍ وَجَدَ غُصْنَ شَوْكٍ عَلَى الطَّرِيقِ فَأَخَّرَهُ فَشَكَرَ اللَّهُ لَهُ فَغَفَرَ لَهُ " . وَقَالَ " الشُّهَدَاءُ خَمْسَةٌ الْمَطْعُونُ وَالْمَبْطُونُ وَالْغَرِقُ وَصَاحِبُ الْهَدْمِ وَالشَّهِيدُ فِي سَبِيلِ اللَّهِ عَزَّ وَجَلَّ " .
