The Makkan Period, Part 3: The Religious Background of Arabia
Section 5 of 16 · The Life of the Prophet Muhammad: The Makkan Period
How the Jewish Faith Reached Arabia
What about the Jewish faith and Christianity? The king of Yemen, Tubbaʿ Asʿad, was travelling to do business in al-Shām, and he passed next to Madīnah, and he left his son in Madīnah to do business until he comes back from Syria. The people of Madīnah killed his son. So when Tubbaʿ Asʿad came back and heard the news that his son was killed, he decided to destroy Madīnah. So he attacked, and his army was overwhelming compared to the small army of Madīnah. So he could have crushed his opposition, but two Jewish rabbis came out of Madīnah.
Now, how did Jews get there in the first place? When the Romans destroyed Jerusalem, the Jews dispersed. There were some of them who came down into Arabia in search of the promised land, where the Nabī would be sent, because they had in their books signs of the awaited prophet. So they were looking for the place where he would immigrate to. They saw these signs in Madīnah, and in a few other places, in Khaybar and other places. So this is where the Jews settled, because these places had the resemblances, or the signs, of the place where the prophet would be sent. That is why they settled in Madīnah. Three Jewish tribes: there were Banū Qaynuqāʿ, Banū al-Naḍīr and Banū Qurayẓah. So that's how they reached Madīnah. So they were ethnically Jewish, who immigrated when the Romans sacked Jerusalem.
So these two Jewish rabbis, they came out, and they came to Tubbaʿ Asʿad, and they told him, "This place is protected by God. If you attempt to destroy it, Allah will destroy you." And they were able to convince Tubbaʿ Asʿad. Tubbaʿ Asʿad not only agreed to withdraw his army and stop attacking Madīnah, but he also was impressed by the religion and wanted to become Jewish himself. And then he invited these two Jewish rabbis to go with him to Yemen, and they agreed, and he became Jewish.
