(47) باب غِلَظِ تَحْرِيمِ قَتْلِ الإِنْسَانِ نَفْسَهُ وَإِنَّ مَنْ قَتَلَ نَفْسَهُ بِشَيْءٍ عُذِّبَ بِهِ فِي النَّارِ وَأَنَّهُ لاَ يَدْخُلُ الْجَنَّةَ إِلاَّ نَفْسٌ مُسْلِمَةٌ
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
