I asked you a few days ago but I got no response and I really need one. I love the qur'an and I think it's a beautifully written book. I am also on the edge of converting to Islam. However I do not understand aya 9:30. It talks about the Jews taking Uzair as God's son. But I've neve met a Jew who believes that. Also it seems to speak illy of Chrisitans and Jews which I don't understand because in the other areas of the Qur'an it speaks highly of them. Please please please explain this to me because there is no one else who can. My parents are catholic and so they don't know much about Islam as you or another Muslim might. Thank you so much.
In responding to your question, I cannot do any better than quoting Muhammad Asad's comment on the above verse. First, let me his rendition of the verse, followed by his note on it, for clarification. The late Muhammad Asad was a convert from Judaism to Islam, who spent decades to the study of the Qur'an.
9:30 (Asad) AND THE JEWS say, "Ezra is God's son," while the Christians say, "The Christ is God's son." Such are the sayings which they utter with their mouths, following in spirit assertions made in earlier times by people who denied the truth!  [They deserve the imprecation:] "May God destroy them!" How perverted are their minds!
Note 44 (Quran Ref: 9:30 )
Furthermore, the Qur'anic denunciations of the Jews for their acts of disobedience have parallels in the Bible: see, for instance, Psalms 109:17-20, 78:21-22, 69:27-28 and in Mathew 23:33 and 12:34 (cf. Yahya Emerick, The Meaning of the Holy Qur'an in Today's English, p.194).
