Silsilah as-Sahihah 2660 — Mutual love and compassion among Muslims

It is narrated from Sayyiduna Nu’man bin Bashir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: “In mutual love, mercy, and compassion for one another, the example of the believers is like that of a single body: when one limb suffers, the whole body responds with wakefulness and fever.”
