Abu Hurairah reported,

The Prophet ﷺ said, "Whoever throws himself off a mountain and kills himself will be in the fire of Hell, throwing himself down within it, abiding there eternally and forever. Whoever swallows poison and kills himself will have his poison in his hand, sipping it in the fire of Hell, abiding there eternally and forever. Whoever kills himself with a piece of iron will have his iron in his hand, stabbing himself with it in his belly in the fire of Hell, abiding there eternally and forever."

عن أبي هريرة

عن النبي ﷺ قال: من تردى من جبل فقتل نفسه فهو في نار جهنم يتردى فيه خالدا مخلدا فيها أبدا، ومن تحسى سما فقتل نفسه فسمه في يده يتحساه في نار جهنم نار جهنم خالدا مخلدا فيها أبدا، ومن قتل نفسه بحديدة فحديدته في يده يجأ بها في بطنه في خالدا مخلدا فيها أبدا.
