Greater Israel
Bani Israel, or the Jews, were the Chosen People of God. They were given Palestine, the old one that included major parts of the Middle East. Later, because of their misdeeds, God exiled them from these lands. Now they are trying to regain the whole area, but international laws and treaties do not allow them to do so. They gain what they can when they find an opportunity. Mehdi was an imaginary figure whose idea became popular among Muslims. The second coming of Jesus is mentioned in some traditions from the Holy Prophet; however, Ghamidi saheb did not accept them on their face value, because the Quran had announced the death of Jesus. For details, please watch the series Imam Mehdi and Second Coming of Jesus by Ghamidi saheb. https://youtu.be/8bVM-OHYiKQ?si=wrIHYzv6QwOGOzfj
It is not speculation. Dajjal will help Jews attain this goal of theirs, and the true followers of Jesus will counter him along with Muslims.
