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] (Unapproved Hadith).

وعن صفوان بن عسال رضي الله عنه قال: قال يهودي لصاحبه: اذهب بنا إلي هذا النبي ﷺ الله عليه وسلم فأتيا رسول الله ﷺ ، فسألاه عن تسع آيات بينات؛ فذكر الحديث إلي قوله: فقبلا يده ورجله، وقالا: نشهد أنك نبي. ((رواه الترمذي وغيره بأسانيد صحيحة)).
