a man killed himself with an arrowhead and the Messenger of Allah said: "As for me, I will not pray for him."  

رَسُولُ اللَّهِ ﷺ أَمَّا أَنَا فَلاَ أُصَلِّي عَلَيْهِ  

"Whoever throws himself, he will be in the Fire of Hell, throwing himself down forever and ever. And whoever kills himself with a piece of iron"- then I missed something ( one of the narrators) Khalid said-"will have his piece of iron in his hand, stabbing himself in the stomach in the Fire of Hell, forever and ever."  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ تَرَدَّى مِنْ جَبَلٍ فَقَتَلَ نَفْسَهُ فَهُوَ فِي نَارِ جَهَنَّمَ يَتَرَدَّى 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 عَلَىَّ شَىْءٌ خَالِدٌ يَقُولُ كَانَتْ حَدِيدَتُهُ فِي يَدِهِ يَجَأُ بِهَا فِي بَطْنِهِ فِي نَارِ جَهَنَّمَ خَالِدًا مُخَلَّدًا فِيهَا أَبَدًا
