English translation
6045. Narrated Abū Dhar رَضِيَ اللَّهُ عَنْهُ that he heard the Prophet ﷺ saying, "If somebody accuses another of Fusūq (by calling him 'Fāsiq' i.e., a wicked person) or accuses him of Kufr (disbelief), such an accusation will revert to him (i.e., the accuser) if his companion (the accused) is innocent."
