Narrated Safwan bin Assal: "A Jew said to his companion: 'Accompany us to this Prophet.' So his companion said: 'Do not say: "Prophet". For if he hears you (say that) then he will be very happy.' So they went to the Messenger of Allah (ﷺ) to question him about nine clear signs. So he said to them: 'Do not associate anything with Allah, nor steal, nor commit unlawful intercourse, nor take a life which Allah has made prohibited prohibited, except for what is required (in the law), nor hasten to damage the reputation of one of power so that he will be killed, nor practice magic, nor consume Riba, nor falsely accuse the chaste woman, nor turn to flee on the day of the march, and for you Jews particularly, to not violate the Sabbath.'" He said: "So they kissed his hands and his feet, and they said: 'We bear witness that you are a Prophet.' So he (ﷺ) said: 'Then what prevents you from following me?' They said: 'Because Dawud supplicated to his Lord that his offspring never be devoid of Prophets and we feared that if we follow you then the Jews will kill us.'"
