Clarifying the emphatic prohibition against killing oneself; The one who kills himself with something will be punished with it in the fire; And that no one will enter Paradise but a muslim
حَدَّثَنِي أَبُو غَسَّانَ الْمِسْمَعِيُّ، حَدَّثَنَا مُعَاذٌ، - وَهُوَ ابْنُ هِشَامٍ - قَالَ حَدَّثَنِي أَبِي، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، قَالَ حَدَّثَنِي أَبُو قِلاَبَةَ، عَنْ ثَابِتِ بْنِ الضَّحَّاكِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " لَيْسَ عَلَى رَجُلٍ نَذْرٌ فِيمَا لاَ يَمْلِكُ وَلَعْنُ الْمُؤْمِنِ كَقَتْلِهِ وَمَنْ قَتَلَ نَفْسَهُ بِشَىْءٍ فِي الدُّنْيَا عُذِّبَ بِهِ يَوْمَ الْقِيَامَةِ وَمَنِ ادَّعَى دَعْوَى كَاذِبَةً لِيَتَكَثَّرَ بِهَا لَمْ يَزِدْهُ اللَّهُ إِلاَّ قِلَّةً وَمَنْ حَلَفَ عَلَى يَمِينِ صَبْرٍ فَاجِرَةٍ " .
It is narrated on the authority of Thabit b. al-Dahhak that the Messenger of Allah (ﷺ) observes: None is obliged to give votive offering (of a thing) which is not in his possession and the cursing of a believer is tantamount to killing him, and he who killed himself with a thing in this world would be tormented with that (very thing) on the Day of Resurrection, and he who made a false claim to increase (his wealth), Allah would make no addition but that of paucity, and he who perjured would earn the wrath of God
