Arabic (Original)
حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ قَالَ حَدَّثَنَا هِشَامٌ وَيَزِيدُ قَالَ أَخْبَرَنَا هِشَامٌ قَالَ حَدَّثَنِي يَحْيَى عَنْ أَبِي قِلَابَةَ عَنْ ثَابِتِ بْنِ الضَّحَّاكِ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَعْنُ الْمُؤْمِنِ كَقَتْلِهِ وَمَنْ قَتَلَ نَفْسَهُ بِشَيْءٍ فِي الدُّنْيَا عُذِّبَ بِهِ فِي الْآخِرَةِ وَلَيْسَ عَلَى رَجُلٍ مُسْلِمٍ نَذْرٌ فِيمَا لَا يَمْلِكُ وَمَنْ رَمَى مُؤْمِنًا بِكُفْرٍ فَهُوَ كَقَتْلِهِ وَمَنْ حَلَفَ بِمِلَّةٍ سِوَى الْإِسْلَامِ كَاذِبًا فَهُوَ كَمَا قَالَ.
English Translation
Yahya ibn Sa'id told us: Hisham and Yazid told us - Yazid said: Hisham informed us - who said: Yahya told me, from Abu Qilaba, from Thabit ibn al-Dahhak, that the Prophet, peace and blessings be upon him, said: "Cursing a believer is like killing him. Whoever kills himself with something in this world will be punished with it in the Hereafter. There is no vow upon a Muslim man in what he does not possess. Whoever accuses a believer of disbelief, it is like killing him. And whoever swears falsely by a religion other than Islam, then he is as he said."
