It is narrated from Sayyiduna Nu'man bin Bashir (may Allah be pleased with him) that indeed the Messenger of Allah (peace and blessings be upon him) said: "Surely, in maintaining mutual relations, showing mercy and kindness among themselves, and in that which Allah has ordained between them, the example of the Muslims is like that of a body; when any part of it is afflicted with pain, the whole body becomes restless and suffers from sleeplessness and fever."

Hadith Takhrij«إسناده ضعيف ، جز من حديث لوين : 108 ، معجم الشيوخ : 417» وليد بن ابی ثور ضعیف ہے ۔
Brief Explanation
Explanation: The meaning is that just as when any part of the body is in pain, the entire body is affected by that pain, and due to the suffering of merely one part, the whole body becomes afflicted, in the same way, all the Muslims of the world should also, erasing all distinctions of color and race, differences and disparities of language and culture, and all kinds of differences of lineage, tribes, and regions, become like a single body. If any Muslim is harmed, then all Muslims should share in his pain and sorrow, and together, they should strive to remove his suffering and hardship.
