Arabic hadith text
حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا جَرِيرٌ، عَنْ فُضَيْلِ بْنِ غَزْوَانَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَيُّمَا رَجُلٍ مُسْلِمٍ أَكْفَرَ رَجُلاً مُسْلِمًا فَإِنْ كَانَ كَافِرًا وَإِلاَّ كَانَ هُوَ الْكَافِرَ " .
Translation
Uthman ibn Abi Shaybah narrated to us; Jarir narrated to us, from Fudayl ibn Ghazwan, from Nafi, from Ibn Umar, who said: The Messenger of Allah said: ‘If a Muslim man calls another Muslim man an unbeliever, then if that man is an unbeliever, [the description is true]; otherwise, the one who said it is himself an unbeliever.’
