The Prophet ﷺ said, "He who commits suicide by throttling shall keep on throttling himself in the Hell Fire (forever) and he who commits suicide by stabbing himself shall keep on stabbing himself in the Hell-Fire."  

قَالَ النَّبِيُّ ﷺ الَّذِي يَخْنُقُ نَفْسَهُ يَخْنُقُهَا فِي النَّارِ وَالَّذِي يَطْعُنُهَا يَطْعُنُهَا فِي النَّارِ  

[Machine] From the Prophet ﷺ who harms himself, it is as if he harms himself in the fire. And the one who throws himself into it, it is as if he throws himself into the fire. And the one who strangles himself, it is as if he strangles himself in the fire.  

عَنِ النَّبِيِّ ﷺ الَّذِي يَطْعَنُ نَفْسَهُ إِنَّمَا يَطْعَنُهَا فِي النَّارِ وَالَّذِي يَتَقَحَّمُ فِيهَا يَتَقَحَّمُ فِي النَّارِ وَالَّذِييَخْنُقُ نَفْسَهُ يَخْنُقُهَا فِي النَّارِ  

"الَّذي يَخْنُقُ نَفْسَهُ يَخْنُقُ نَفْسَهُ فِي النَّارِ، والَّذِى يَقْتَحِمُ يَقْتَحِمُ في النَّارِ، والَّذِى يَطعَنُ نَفْسَهُ يَطَعَنُ نَفْسَهُ فِي النَّارِ" .
