The Mutual Mercy, Compassion And Support Of The Believers
Sahih Muslim
حَدَّثَنِي مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا حُمَيْدُ بْنُ عَبْدِ الرَّحْمَنِ، عَنِ الأَعْمَشِ، عَنْ خَيْثَمَةَ، عَنِ النُّعْمَانِ بْنِ بَشِيرٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " الْمُسْلِمُونَ كَرَجُلٍ وَاحِدٍ إِنِ اشْتَكَى عَيْنُهُ اشْتَكَى كُلُّهُ وَإِنِ اشْتَكَى رَأْسُهُ اشْتَكَى كُلُّهُ " .
Nu'man b. Bashir reported that Muslims are like one body of a person; if the eye is sore, the whole body aches, and if the head aches, the whole body aches.
