"The Messenger of Allah said: 'Whoever swears by a religion other than Islam, telling a lie, will be as he said.'" In his narration, Qutaibah said: "Intentionally." Yazid said: "Telling a lie will be as he said, and whoever kills himself with something. Allah will punish him with it in the Fire of Hell."
قَالَ رَسُولُ اللَّهِ ﷺ مَنْ حَلَفَ بِمِلَّةٍ سِوَى الإِسْلاَمِ كَاذِبًا فَهُوَ كَمَا قَالَ قَالَ قُتَيْبَةُ فِي حَدِيثِهِ مُتَعَمِّدًا وَقَالَ يَزِيدُ كَاذِبًا فَهُوَ كَمَا قَالَ وَمَنْ قَتَلَ نَفْسَهُ بِشَىْءٍ عَذَّبَهُ اللَّهُ بِهِ فِي نَارِ جَهَنَّمَ
