حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ حَدَّثَنَا عَبْدُ الصَّمَدِ بْنُ عَبْدِ الْوَارِثِ حَدَّثَنَا أَبِي حَدَّثَنَا حُسَيْنٌ الْمُعَلِّمُ عَنْ ابْنِ بُرَيْدَةَ عَنْ يَحْيَی بْنِ يَعْمَرَ أَنَّ أَبَا الْأَسْوَدِ حَدَّثَهُ عَنْ أَبِي ذَرٍّ أَنَّهُ سَمِعَ رَسُولَ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ لَيْسَ مِنْ رَجُلٍ ادَّعَی لِغَيْرِ أَبِيهِ وَهُوَ يَعْلَمُهُ إِلَّا کَفَرَ وَمَنْ ادَّعَی مَا لَيْسَ لَهُ فَلَيْسَ مِنَّا وَلْيَتَبَوَّأْ مَقْعَدَهُ مِنْ النَّارِ وَمَنْ دَعَا رَجُلًا بِالْکُفْرِ أَوْ قَالَ عَدُوَّ اللَّهِ وَلَيْسَ کَذَلِکَ إِلَّا حَارَ عَلَيْهِ
صحیح مسلم · Hadith 217
It is reported on the authority of Ibn 'Umar that the Messenger of Allah (may peace and blessings be upon him) said: Any person who called his brother: O unbeliever (has in fact done an act by which this unbelief) would return to one of them. If it were so, as he asserted (then the unbelief of man was confirmed but if it was not true), then it returned to him (to the man who labeled it on his brother Muslim).
