a man killed himself with an arrowhead and the Messenger of Allah said: "As for me, I will not pray for him." (Using translation from Nasāʾī 1964)  

رَسُولُ اللهِ ﷺ «أَمَّا أَنَا فَلَا أُصَلِّي عَلَيْهِ»  

The Prophet ﷺ 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 ʿAbdomen with it in the (Hell) Fire wherein he will abide eternally forever." (Using translation from Bukhārī 5778)  

عَنِ النَّبِيِّ ﷺ قَالَ «مَنْ تَرَدَّى مِنْ جَبَلٍ فَقَتَلَ نَفْسَهُ فَهُوَ فِي نَارِ جَهَنَّمَ يَتَرَدَّى فِيهَا خَالِدًا مُخَلَّدًا فِيهَا أَبَدًا وَمَنْ تَحَسَّى سُمًّا فَقَتَلَ نَفْسَهُ فَسُمُّهُ فِي يَدِهِ يَتَحَسَّاهُ فِي نَارِ جَهَنَّمَ خَالِدًا مُخَلَّدًا فِيهَا أَبَدًا وَمَنْ قَتَلَ نَفْسَهُ بِحَدِيدَةٍ ثُمَّ انْقَطَعَ عَلَيَّ شَيْءٌ يَعْنِي خَالِدًا كَانَتْ حَدِيدَتُهُ فِي يَدِهِ يَجَأُ بِهَا فِي بَطْنِهِ فِي نَارِ جَهَنَّمَ خَالِدًا مُخَلَّدًا فِيهَا أَبَدًا»
