Uzair (Arabic: عزير, ʿUzayr) is a figure mentioned in the Quran, in the verse 9:30, which states that he was revered by the Jews as "the son of God". Uzair is most often identified with the biblical Ezra.
Those who claim that Uzair is son of God are condemned in Quran as those who claim that Maseeh (Jesus) is son of God.
Jews have many different sects and divisions in faith and we don't condemn but only those who went away from the real message of Torah and adverse stand against any prophet.
We read in Quran about the People of Book ( Not all of them are alike, a community from the People of Book stand for the right, they recite the Verses of Allah in parts of the night during prostrating to God. (Sura 3, Verse 113).
Allah (SWT) tells us in Quran to call the People of Book for common word between us and them (Say: O People of Bok, come to a common word between us and you, that we worship none but Allah and we do never associate any partner with Him) (3: 64)
This claim of some Jewish people that Uzair is son of Allah (SWT) , was common among Jewish communities in Yemen and Madina during the time of the Prophet Muhammad ( SAWA). There is Jewish sect called Asbahaniyyah which was also claiming the same. That is why, when the Prophet Muhammad (SAWA) recited the Quranic verse on them, none of Jewish people denied it, despite all their enmity against Quran and Islam. If it was not among them, it would have been a golden chance for them to attack their enemy, the Prophet Muhammad, but they admitted it because it was among them at that time.
The Jewish people kept on changing their texts all along the history till now. They have now removed that claim from most of their books which are available to the public, but that does not mean that it was not their at the time of the Prophet Muhammad (SAWA). Their admitting and not objecting or denying it is a very clear evidence that it was a fact.
