It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Do not ask the People of the Book about anything, for they will never guide you, while they themselves have gone astray. In this matter, you will either have to affirm falsehood or deny the truth. So indeed, if Musa (peace be upon him) were alive among you, it would not be permissible for him except to follow me."
