حَدَّثَنَا أَصْبَغُ قَالَ‏:‏ أَخْبَرَنِي ابْنُ وَهْبٍ قَالَ‏:‏ أَخْبَرَنِي خَالِدُ بْنُ حُمَيْدٍ، عَنْ خَالِدِ بْنِ يَزِيدَ، عَنْ سُلَيْمَانَ بْنِ رَاشِدٍ، عَنْ عَبْدِ اللهِ بْنِ رَافِعٍ، عَنْ أَبِي هُرَيْرَةَ قَالَ‏:‏ الْمُؤْمِنُ مَرْآةُ أَخِيهِ، إِذَا رَأَى فِيهَا عَيْبًا أَصْلَحَهُ‏.‏

Abu Hurayra reported that the Prophet, may Allah bless him and grant him peace, said, "A believer is the mirror of his brother. A believer is the brother of another believer. He protects him against loss and defends him behind his back."
