Sahih Bukhari Volume 7, Book 76, Hadith 5780

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الْوَهَّابِ، حَدَّثَنَا خَالِدُ بْنُ الْحَارِثِ، حَدَّثَنَا شُعْبَةُ، عَنْ سُلَيْمَانَ، قَالَ سَمِعْتُ ذَكْوَانَ، يُحَدِّثُ عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ مَنْ تَرَدَّى مِنْ جَبَلٍ فَقَتَلَ نَفْسَهُ، فَهْوَ فِي نَارِ جَهَنَّمَ، يَتَرَدَّى فِيهِ خَالِدًا مُخَلَّدًا فِيهَا أَبَدًا، وَمَنْ تَحَسَّى سَمًّا فَقَتَلَ نَفْسَهُ، فَسَمُّهُ فِي يَدِهِ، يَتَحَسَّاهُ فِي نَارِ جَهَنَّمَ خَالِدًا مُخَلَّدًا فِيهَا أَبَدًا، وَمَنْ قَتَلَ نَفْسَهُ بِحَدِيدَةٍ، فَحَدِيدَتُهُ فِي يَدِهِ، يَجَأُ بِهَا فِي بَطْنِهِ فِي نَارِ جَهَنَّمَ خَالِدًا مُخَلَّدًا فِيهَا أَبَدًا ‏"‏‏

Narrated By Abu Huraira : The Prophet said, "Whoever purposely throws himself from a mountain and kills himself, will be in the (Hell) Fire falling down into it and abiding therein perpetually forever; and whoever drinks poison and kills himself with it, he will be carrying his poison in his hand and drinking it in the (Hell) Fire wherein he will abide eternally forever; and whoever kills himself with an iron weapon, will be carrying that weapon in his hand and stabbing his abdomen with it in the (Hell) Fire wherein he will abide eternally forever."
