Political do you believe Ezekiel (Dhūlkifl) was a prophet as mentioned in the Qu'ran? If so then you need to go read his book because God makes it clear throughout it that the land of Israel belongs to the sons of Jacob. Since Muhammad believed in Ezekiel, and he was not a son of Jacob, why do you argue with God? Why didn't Muhammad himself go conquer it? No, instead the early Muslims did this, not Muhammad. Wasn't he the perfect exemplar of how Muslims are supposed to act?
