Sahih al-Bukhari 6652

Arabic

حَدَّثَنَا مُعَلَّى بْنُ أَسَدٍ، حَدَّثَنَا وُهَيْبٌ، عَنْ أَيُّوبَ، عَنْ أَبِي قِلاَبَةَ، عَنْ ثَابِتِ بْنِ الضَّحَّاكِ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ مَنْ حَلَفَ بِغَيْرِ مِلَّةِ الإِسْلاَمِ فَهْوَ كَمَا قَالَ ـ قَالَ ـ وَمَنْ قَتَلَ نَفْسَهُ بِشَىْءٍ عُذِّبَ بِهِ فِي نَارِ جَهَنَّمَ، وَلَعْنُ الْمُؤْمِنِ كَقَتْلِهِ، وَمَنْ رَمَى مُؤْمِنًا بِكُفْرٍ فَهْوَ كَقَتْلِهِ ‏"‏‏.‏

Translation

Narrated Thabit bin Ad-Dahhak:The Prophet (ﷺ) said, "Whoever swears by a religion other than Islam, is, as he says; and whoever commits suicide with something, will be punished with the same thing in the (Hell) Fire; and cursing a believer is like murdering him; and whoever accuses a believer of disbelief, then it is as if he had killed him
