The Messenger of Allah ﷺ said, "Whoever throws himself off a mountain and kills himself will be in the Fire of Hell, throwing himself down within it forever and ever. Whoever drinks poison and kills himself will hold his poison in his hand, sipping it in the Fire of Hell forever and ever. And whoever kills himself with a blade will hold that blade in his hand, stabbing it into his belly in the Fire of Hell forever and ever."
قال رسول الله ﷺ: من تردي 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 خالدا مخلدا فيها أبدا، ومن قتل نفسه بحديدة فحديدته في يده يجأ بها في بطنه في نار جهنم خالدا مخلدا فيها أبدا.
Bukhari related it in the Book of Medicine (5778), and Muslim in the Book of Faith (109: 175), both from the hadith of Sulayman Amash, who said, I heard Zakwan narrating from Abu Hurairah, and he related it.
