BE CONCERNED FOR OTHER MUSLIMS H 225 "In their mutual love, kindness, and compassion towards each other, Muslims can be compared to the human body; when one of its limbs is afflicted the whole of it is affected in its waking and fever." R 225 Bukhari and Muslim with a chain up to Nu'man son of Bashir who related that the Messenger of Allah, praise and peace be upon him, said this.
224- وعن النعمان بن بشير رضي الله عنهما ، قَالَ : قَالَ رَسُول الله صلى الله عليه وآله وسلم : "مَثَلُ المُؤْمِنينَ في تَوَادِّهِمْ وتَرَاحُمهمْ وَتَعَاطُفِهمْ ، مَثَلُ الجَسَدِ إِذَا اشْتَكَى مِنْهُ عُضْوٌ تَدَاعَى لَهُ سَائِرُ الجَسَدِ بِالسَّهَرِ والحُمَّى" مُتَّفَقٌ عَلَيهِ .
