He who took deliberately a false oath on a religion other than Islam would become that which he had professed. And he who killed himself with anything Allah would torment him with that in the Fire of Hell.
Sahih Muslim Book 1, Hadith 210
← Previous Hadith 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

Sahih Muslim Book 1, Hadith 209 Next Hadith → Verily the Messenger of Allah (ﷺ) said: He who took an oath on a religion other than Islam as a liar would become so as he said, and he who slaughtered himself with a thing would be slaughtered with that on the Day of Resurrection.

Sahih Muslim Book 1, Hadith 211
