Arabic (Original)
حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ عَنْ زَكَرِيَّا قَالَ حَدَّثَنَا عَامِرٌ قَالَ سَمِعْتُ النُّعْمَانَ بْنَ بَشِيرٍ يَخْطُبُ يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ مَثَلُ الْمُؤْمِنِينَ فِي تَوَادِّهِمْ وَتَعَاطُفِهِمْ وَتَرَاحُمِهِمْ مَثَلُ الْجَسَدِ إِذَا اشْتَكَى مِنْهُ شَيْءٌ تَدَاعَى لَهُ سَائِرُ الْجَسَدِ بِالسَّهَرِ وَالْحُمَّى.
English Translation
Yahya b. Sa'id told us, from Zakariyya, who said: Amir told us, he said: I heard al-Nu'man b. Bashir delivering a sermon, saying: I heard the Messenger of Allah, peace and blessings be upon him, say: "The likeness of the believers in their mutual love, mutual compassion, and mutual mercy is that of a single body: when one part of it complains, the rest of the body responds to it with sleeplessness and fever."
