Musnad Ahmad 624:8

Yahya ibn Sa’id narrated to us, from Shu’bah, ‘Amr ibn Murrah narrated to me, from ‘Abdullah ibn Salamah, from Safwan ibn ‘Assal, who said: A man from the Jews said to another: "Let us go to this Prophet." The other said: "Do not call him that, for if he heard it, he would have four eyes." He said: So we went to him and asked him about this verse: {And We certainly gave Moses nine clear signs} [Al-Isra: 101]. He said: "Do not associate anything with Allah, do not kill the soul which Allah has forbidden except by right, do not steal, do not commit adultery, do not flee from the battlefield, do not practice sorcery, do not consume usury, and do not lead an innocent person to a person of authority so that he may kill him. And upon you, specifically, O Jews, is that you do not transgress on the Sabbath." They both said: "We bear witness that you are the Messenger of Allah, may Allah bless him and grant him peace."
