Sahih Muslim 2589
حَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ، وَقُتَيْبَةُ، وَابْنُ، حُجْرٍ قَالُوا حَدَّثَنَا إِسْمَاعِيلُ، عَنِ الْعَلاَءِ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " أَتَدْرُونَ مَا الْغِيبَةُ " . قَالُوا اللَّهُ وَرَسُولُهُ أَعْلَمُ . قَالَ " ذِكْرُكَ أَخَاكَ بِمَا يَكْرَهُ " . قِيلَ أَفَرَأَيْتَ إِنْ كَانَ فِي أَخِي مَا أَقُولُ قَالَ " إِنْ كَانَ فِيهِ مَا تَقُولُ فَقَدِ اغْتَبْتَهُ وَإِنْ لَمْ يَكُنْ فِيهِ فَقَدْ بَهَتَّهُ " .
Yahya ibn Ayyub, Qutaybah, and Ibn Hujr narrated to us; they said: Ismail narrated to us, from al-Ala, from his father, from Abu Huraira, that the Messenger of Allah (peace and blessings be upon him) said: Do you know what backbiting is? They said: Allah and His Messenger know best. He said: It is your mentioning your brother in a way he dislikes. He was asked: What if what I say about my brother is true? He said: If what you say is true, you have backbitten him; if it is not true, you have slandered him.
