Abu Barzah al-Aslami reported: The Messenger of Allah, peace and blessings be upon him, said, “O you who have faith with their tongues but faith has not entered their hearts! Do not backbite the Muslims or seek their faults. Whoever seeks their faults, Allah will seek his faults. And if Allah seeks his faults, He will expose him even in the privacy of his own house.”

عَنْ أَبِي بَرْزَةَ الأَسْلَمِيِّ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَا مَعْشَرَ مَنْ آمَنَ بِلِسَانِهِ وَلَمْ يَدْخُلِ الإِيمَانُ قَلْبَهُ لاَ تَغْتَابُوا الْمُسْلِمِينَ وَلاَ تَتَّبِعُوا عَوْرَاتِهِمْ فَإِنَّهُ مَنِ اتَّبَعَ عَوْرَاتِهِمْ يَتَّبِعِ اللَّهُ عَوْرَتَهُ وَمَنْ يَتَّبِعِ اللَّهُ عَوْرَتَهُ يَفْضَحْهُ فِي بَيْتِهِ
