The History of Yathrib

The Ausan Khaziraj settled down in Yathrib and the two of them benefited each other. How so? They who were skilled in agriculture, in weaving. Of course they were businessmen. The Arabs had knowledge of war. And so the Arabs sized the Jews. So all of the Jews began speaking fluent Arabic. Now they still spoke Hebrew by the way. We know this from the Syrah. But they kept much of their culture and they adopted Arab culture.
