When do the Jews rise for the first time and the second time, and are the hadiths on the virtues of the people of the East authentic?

Allah Almighty stated that the Children of Israel would cause corruption on earth twice and attain great dominance. However, no evidence specifies the time of this dominance. Victory over the Jews is coming, for Muslim narrated that the Prophet, peace and blessings be upon him, said: "The Hour will not be established until the Muslims fight the Jews, and the Muslims will kill them." There is evidence that the victory of the Muslims will come from the East with the appearance of the Mahdi and the emergence of black banners from the East, as the Prophet, peace and blessings be upon him, said: "If you see him, pledge allegiance to him, even if you have to crawl over snow, for he is the Caliph of Allah, the Mahdi." Ibn Kathir said that the treasure mentioned refers to the treasure of the Kaaba, and that the Mahdi will be supported by people from the East who will assist him, and their banners will be black.
