Uzayr - most often identified with the Judeo-Christian Ezra (عزير, 'Uzair) - is a figure mentioned in the Qur'an, in the verse 9:30, which states that he was revered by the Jews as "the son of God". Historically, Muslim scholars have interpreted this verse as referring to a small group of Jews making such a reverence.
Although not explicitly mentioned in the Quran among the prophets, Ezra is considered as one by some Muslim scholars, based on Islamic traditions. Ezra lived between the times of King Solomon and the time of Zachariah, father of John the Baptist.
On the other hand, Muslim scholars such as Mutahhar al-Maqdisi and Djuwayni and notably Ibn Hazm and al-Samaw'al accused Ezra (or one of his disciples) of falsification of the Torah. Several sources state that the Qur'an refers to Jews who began to call Ezra a "son of God" due to his religious achievements coupled with the misunderstanding of his position in the Jewish faith as a Bene Elohim.
Other western scholars, relying on exegetical material from Ibn Abbas and Ibn Qutaybah, consider Uzayr not to be Ezra but Azariah, mentioned in the book of Daniel as Abednego.
