حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا زَكَرِيَّاءُ، عَنْ عَامِرٍ، قَالَ سَمِعْتُهُ يَقُولُ سَمِعْتُ النُّعْمَانَ بْنَ بَشِيرٍ، يَقُولُ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " تَرَى الْمُؤْمِنِينَ فِي تَرَاحُمِهِمْ وَتَوَادِّهِمْ وَتَعَاطُفِهِمْ كَمَثَلِ الْجَسَدِ إِذَا اشْتَكَى عُضْوًا تَدَاعَى لَهُ سَائِرُ جَسَدِهِ بِالسَّهَرِ وَالْحُمَّى ".

Narrated An-Nu`man bin Bashir:Allah's Messenger (ﷺ) said, "You see the believers as regards their being merciful among themselves and showing love among themselves and being kind, resembling one body, so that, if any part of the body is not well then the whole body shares the sleeplessness (insomnia) and fever with it
