Musannaf Ibn Abi Shaybah 37135 — Reports from our Prophet

Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) reports from the Prophet (peace and blessings be upon him) that he (peace and blessings be upon him) said: "The believer is to the (other) people of faith as the head is to the body. The believer feels the pain of the people of faith just as the rest of the body feels the pain of the head."
