The Messenger of Allah ﷺ said, "The martyrs are five, the one who dies of plague, the one who dies of a stomach ailment, the one who drowns, the one who dies under a collapsing building, and the one martyred in the path of Allah."
و قال الشهداء خمسة المطعون والمبطون والغرق وصاحب الهدم والشهيد في سبيل الله
