Abu Hurairah reported,

The Messenger of Allah ﷺ said, "While a man was walking along a road, he found a thorny branch in the way and removed it. Allah was pleased with him for that and forgave him."He also said, "Martyrs are of five kinds: the one who dies of plague, the one who dies of an abdominal illness, the one who drowns, the one who is killed by a collapsing structure, and the one martyred in the cause of Allah ."

حدثنا يحيى بن يحيى قال قرأت على مالك عن سمي عن أبي صالح

عن أبي هريرة

أن رسول الله ﷺ قال بينما رجل يمشي بطريق وجد غصن شوك على الطريق فأخره فشكر الله له فغفر له وقال الشهداء خمسة المطعون والمبطون والغرق وصاحب الهدم والشهيد في سبيل الله عز وجل
