Musnad Abu Ya'la al-Mawsili 109:136

And from Jabir, he said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Do not ask the People of the Book about anything, for they will not guide you while they have gone astray. You will either believe in a falsehood or deny a truth. And by Allah, if Moses were alive among you, it would not be lawful for him except to follow me."
