Mishkat al-Masabih 58

Safwan b. ‘Assal told how, when a Jew said to his friend, “Let us go to this prophet,” his friend said to him, “Don’t say ‘prophet’, for if he heard you he would be greatly pleased.” [1] They went to God’s messenger and asked him about nine clear signs. God’s messenger said, “Do not associate anything with God. do not steal, do not commit fornication, do not kill anyone whom God has declared inviolate without a just cause, do not bring an innocent person before a ruler in order that he may put him to death, do not use magic, do not devour usury, do not slander a chaste woman, do not turn in flight on the day the army marches, and, a matter which affects you Jews particularly, do not break the Sabbath.” He said that thereupon they kissed/his hands and feet saying, “We testify that you are a prophet.” He asked “What prevents you from following me?” to which they replied, “David prayed to his Lord that prophets might never cease to arise from his offspring, and we are afraid that if we follow you the Jews will kill us.” Tirmidhi, Aba Dawud and Nasa’i transmitted it. [1] Lit. “he would have four eyes.”
