Sahih Muslim 109a
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَأَبُو سَعِيدٍ الأَشَجُّ قَالاَ حَدَّثَنَا وَكِيعٌ، عَنِ الأَعْمَشِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنَ قَتَلَ نَفْسَهُ بِحَدِيدَةٍ فَحَدِيدَتُهُ فِي يَدِهِ يَتَوَجَّأُ بِهَا فِي بَطْنِهِ فِي نَارِ جَهَنَّمَ خَالِدًا مُخَلَّدًا فِيهَا أَبَدًا وَمَنْ شَرِبَ سَمًّا فَقَتَلَ نَفْسَهُ فَهُوَ يَتَحَسَّاهُ فِي نَارِ جَهَنَّمَ خَالِدًا مُخَلَّدًا فِيهَا أَبَدًا وَمَنْ تَرَدَّى مِنْ جَبَلٍ فَقَتَلَ نَفْسَهُ فَهُوَ يَتَرَدَّى فِي نَارِ جَهَنَّمَ خَالِدًا مُخَلَّدًا فِيهَا أَبَدًا " .
Abu Bakr ibn Abi Shaybah and Abu Sa'id al-Ashajj narrated to us; they said: Waki narrated to us, from al-A'mash, from Abu Salih, from Abu Hurayrah, who said: The Messenger of Allah (peace and blessings be upon him) said: ‘Whoever kills himself with an iron weapon will keep thrusting it into his belly in the Fire of Hell, abiding there forever. Whoever drinks poison and kills himself will keep swallowing it in the Fire of Hell, abiding there forever. Whoever throws himself from a mountain and dies will keep falling in the Fire of Hell, abiding there forever.’
