And know that the believers are all one body, just as if one human being suffers from a limb, the rest of the body suffers from a fever. Likewise, if a believer is afflicted by a calamity, his fellow believer is afflicted with it, as if he was the one who was afflicted with it, and he suffers as he suffers. And if the believer does not do that with the believers, the brotherhood of faith is not established between him and them, for God has And be a brother among the believers just as you are a brother among the members of the human body. This is how the proverb came from the Prophet, may God’s prayers and peace be upon him, in the established hadith, which is his saying, may God’s prayers and peace be upon him. “Like the believers in their affection, sympathy, and mercy, like the body. If an organ complains of it, it suffers from it, the body suffers from fever and sleepless nights.
