Sahih al-Bukhari 6047
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا عُثْمَانُ بْنُ عُمَرَ، حَدَّثَنَا عَلِيُّ بْنُ الْمُبَارَكِ، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنْ أَبِي قِلاَبَةَ، أَنَّ ثَابِتَ بْنَ الضَّحَّاكِ، وَكَانَ، مِنْ أَصْحَابِ الشَّجَرَةِ حَدَّثَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " مَنْ حَلَفَ عَلَى مِلَّةٍ غَيْرِ الإِسْلاَمِ فَهْوَ كَمَا قَالَ، وَلَيْسَ عَلَى ابْنِ آدَمَ نَذْرٌ فِيمَا لاَ يَمْلِكُ، وَمَنْ قَتَلَ نَفْسَهُ بِشَىْءٍ فِي الدُّنْيَا عُذِّبَ بِهِ يَوْمَ الْقِيَامَةِ، وَمَنْ لَعَنَ مُؤْمِنًا فَهْوَ كَقَتْلِهِ، وَمَنْ قَذَفَ مُؤْمِنًا بِكُفْرٍ فَهْوَ كَقَتْلِهِ ".
Thabit ibn al-Dahhak, one of those who had pledged allegiance beneath the tree, reported that the Messenger of Allah said: “Whoever swears by a religion other than Islam is as he has said. A son of Adam has no vow concerning what he does not possess. Whoever kills himself with something in this world will be punished with it on the Day of Resurrection. Whoever curses a believer is like one who kills him, and whoever accuses a believer of disbelief is like one who kills him.”
