Reverence towards the Sanctity of the Muslims
وَعَنِ النُّعْمَانِ بْنِ بَشِيرٍ رَضِيَ اَللَّهُ عَنْهُمَا قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ " مَثَلُ الْمُؤْمِنِينَ فِي تَوَادِّهِمْ وَتَرَاحُمِهِمْ وَتَعَاطُفِهِمْ، مَثَلُ الْجَسَدِ إِذَا اشْتَكَى مِنْهُ عُضْوٌ تَدَاعَى لَهُ سَائِرُ الْجَسَدِ بِالسَّهَرِ وَالْحُمَّى” ((مُتَّفَقٌ عَلَيْهِ)) .
Nu'man bin Bashir (May Allah bepleased with them) reported: Messenger of Allah (ﷺ) said, "The believers in their mutual kindness, compassion and sympathy are just like one body. When one of the limbs suffers, the whole body responds to it with wakefulness and fever". [Al-Bukhari and Muslim].
