Ja'far bin Muhammad narrated from his father that Umar bin Khattab (may Allah be pleased with him) mentioned the Magians and said: "I do not know what to do regarding their matter." So Abdur Rahman bin Awf (may Allah be pleased with him) said to him: "I bear witness that I heard the Messenger of Allah (ﷺ) saying: Treat them in the same way as you treat the People of the Book."
