عن أبي الخطاب قتادة قال‏:‏ قلت لأنس‏:‏ أكانت المصافحة في أصحاب رسول الله صلى الله عليه وسلم ‏؟‏ قال‏:‏ نعم‏"‏ ‏(‏‏(‏رواه البخاري‏)‏‏)‏‏.‏

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]
