The Messenger of Allah ﷺ said, "Whoever kills himself with a piece of iron will have that iron in his hand, stabbing himself with it in his stomach in the fire of Hell, dwelling there eternally and forever. And whoever throws himself off a mountain and kills himself will be in the fire of Hell, throwing himself down within it, dwelling there eternally and forever."
حدثنا محمد بن جعفر قال حدثنا شعبة عن سليمان عن ذكوان
أن رسول الله ﷺ قال من قتل نفسه بحديدة فحديدته بيده يجأ بها في بطنه في نار جهنم خالدا مخلدا فيها أبدا ومن تردى من جبل فقتل نفسه فهو في نار جهنم يتردى فيها خالدا مخلدا فيها أبدا
