بَابُ مَنْ قَالَ لأَخِيهِ: يَا كَافِرُChapter: Calling One's Brother "Disbeliever"
Hadith 440
حَدَّثَنَا سَعِيدُ بْنُ دَاوُدَ، قَالَ: حَدَّثَنَا مَالِكٌ، أَنَّ نَافِعًا حَدَّثَهُ، أَنَّ عَبْدَ اللهِ بْنَ عُمَرَ أَخْبَرَهُ، أَنَّ رَسُولَ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: ”إِذَا قَالَ لِلْآخَرِ: كَافِرٌ، فَقَدْ كَفَرَ أَحَدُهُمَا، إِنْ كَانَ الَّذِي قَالَ لَهُ كَافِرًا فَقَدْ صَدَقَ، وَإِنْ لَمْ يَكُنْ كَمَا قَالَ لَهُ فَقَدْ بَاءَ الَّذِي قَالَ لَهُ بِالْكُفْرِ.“
It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "When a person calls another a disbeliever (kafir), then one of them becomes a disbeliever. If the one who was called a disbeliever is truly (because of his sin) a disbeliever, then he (the accuser) has spoken the truth. But if he is not as he was described, then the burden of that statement will fall upon the one who said it, and he will become a disbeliever."
