"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." (Using translation from Nasāʾī 3770)   

قَالَ رَسُولُ اللهِ ﷺ «مَنْ حَلَفَ بِمِلَّةٍ سِوَى الْإِسْلَامِ كَاذِبًا فَهُوَ كَمَا قَالَ وَمَنْ قَتَلَ نَفْسَهُ بِشَيْءٍ عُذِّبَ بِهِ فِي نَارِ جَهَنَّمَ» وَقَالَ قُتَيْبَةُ فِي حَدِيثِهِ بِشَيْءٍ مُتَعَمِّدًا  

"Whoever swears by a religion other than Islam, telling a lie, will be as he said, and whoever kills himself with something will be punished with it in the Hereafter." (Using translation from Nasāʾī 3771)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «مَنْ حَلَفَ بِمِلَّةٍ سِوَى الْإِسْلَامِ كَاذِبًا فَهُوَ كَمَا قَالَ وَمَنْ قَتَلَ نَفْسَهُ بِشَيْءٍ عُذِّبَ بِهِ فِي الْآخِرَةِ»
