Safwan bin 'Assal (May Allah be pleased with him) reported:
A Jew asked his companion to take him to the Prophet (ﷺ); and when they came to the Messenger of Allah (ﷺ), they asked him about the nine clear signs (given to Prophet Musa). Safwan narrated the long Hadith which concludes: They kissed the hands and feet of the Messenger of Allah (ﷺ) and said: "We testify that you are a Prophet."[At-Tirmidhi] (PT)
