عن أبي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ  صلى الله عليه وسلم  قال أَتَدْرُونَ ما الْغِيبَةُ قالوا الله وَرَسُولُهُ أَعْلَمُ قال ذِكْرُكَ أَخَاكَ بِمَا يَكْرَهُ قِيلَ أَفَرَأَيْتَ إن كان في أَخِي ما أَقُولُ قال إن كان فيه ما تَقُولُ فَقَدْ اغْتَبْتَهُ وَإِنْ لم يَكُنْ فيه فَقَدْ بَهَتَّهُ

Abu Hurayrah (rta) reported that God’s Messenger (sws) said: “Do you know what is backbiting?” The companions replied: “God and His Messenger know best.” Thereupon, the Prophet (sws) said: “Backbiting implies you talk about your brother in a manner which he does not like.” It was asked: “What do you say if [the fault] I mention is actually found in my brother?” The Prophet (sws) said: “If it is actually found [in him] you [are guilty of] backbiting, and if it is not found in him, then you [are guilty of] slandering him.”[1]
