Musannaf Ibn Abi Shaybah 28112 — Those who disliked looking into

Sayyiduna Jabir (may Allah be pleased with him) said: Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) came to the Prophet (peace and blessings be upon him) with a page from a book of the People of the Book and said: "O Messenger of Allah (peace and blessings be upon him), I have obtained a very fine book from some of the People of the Book." The narrator said: He (peace and blessings be upon him) became angry and said: "O Ibn al-Khattab, are you still bewildered about this? By the One in whose Hand is my soul, I have brought you a clear and radiant religion. Do not ask the People of the Book about anything, for they may tell you the truth and you deny it, or they may tell you something false and you believe it. By the One in whose Hand is my soul, if even Musa (peace be upon him) were alive today, he would have no option but to follow me."
