The Ezra Deception. Why does Muhammad's god, Allah, declare "The Jews say Ezra is the son of Allah," (Quran 9:30), when the Jewish faith has NEVER asserted this?

Like Muslims, Jews believe that the god of the universe has no son:  From the Jewish holy text Exodus Rabbah 29 we read: "I am the first and I am the last, and beside Me there is no God' I am the first, I have no father; I am the last, I have no brother. Beside Me there is no God; I have no son."
