الْأَدَبُ الْمُفْرَدُ
Al-Adab al-Mufrad 239
Cheerfulness Towards People
A Muslim is the mirror of his brother
حَدَّثَنَا إِبْرَاهِيمُ بْنُ حَمْزَةَ، قَالَ: حَدَّثَنَا ابْنُ أَبِي حَازِمٍ، عَنْ كَثِيرِ بْنِ زَيْدٍ، عَنِ الْوَلِيدِ بْنِ رَبَاحٍ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ: الْمُؤْمِنُ مَرْآةُ أَخِيهِ، وَالْمُؤْمِنُ أَخُو الْمُؤْمِنِ، يَكُفُّ عَلَيْهِ ضَيْعَتَهُ، وَيَحُوطُهُ مِنْ وَرَائِهِ.
Abu Hurayra reported that the Prophet, (ﷺ), 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."
