Ayat 30. And the Jews say: 'Uzair (Ezra) is the son of Allah, and the Christians say: Messiah is the son of Allah. That is a saying from their mouths. They imitate the saying of the disbelievers of old. Allah's Curse be on them, how they are deluded away from the truth!
Ayat 31. They (Jews and Christians) took their rabbis and their monks to be their lords besides Allah (by obeying them in things which they made lawful or unlawful according to their own desires without being ordered by Allah), and (they also took as their Lord) Messiah, son of Maryam (Mary), while they (Jews and Christians) were commanded [in the Taurat (Torah) and the Injeel (Gospel)) to worship none but One Allah (God - Allah) Lâ ilâha illa Huwa (none has the right to be worshipped but He) . Praise and glory be to Him, (far above is He) from having the partners they associate (with Him)."
Hazrat Ubadah bin As-Samit (May Allah be pleased with him) reported: Messenger of Allah [SAWW](PBUH) said, "He who bears witness that there is no true god except Allah, alone having no partner with Him, that Muhammad [SAWW](PBUH) is His slave and His Messenger, that `Isa (Jesus) (PBUH) is His slave and Messenger and he (Jesus) is His Word which He communicated to Maryam (Mary) and His spirit which He sent to her, that Jannah is true and Hell is true; Allah will make him enter Jannah accepting whatever deeds he accomplished". [Al-Bukhari Hadith # 3435 and Muslim Hadith # 043].
Another narration in Muslim is: the Messenger of Allah [SAWW](PBUH) said, "Whosoever testifies that there is no true god except Allah and that Muhammad [SAWW](PBUH) is the Messenger of Allah, Allah (SWT) saves him from the Fire (of Hell)".
Lesson : as mentioned above in Surah At-Taubah Ayat Ayat 30. "And the Jews say: 'Uzair (Ezra) is the son of Allah, and the Christians say: Messiah is the son of Allah. That is a saying from their mouths. They imitate the saying of the disbelievers of old.". This Hadith confirms that all Prophets of Allah were men and thus refutes those who attribute divinity to them and exclude them from the category of men or regard them a part of Allah, as Christians believes Prophet `Isa (Jesus to be Christ) by regarding him Allah or His son, or the Jews do Prophet `Uzair by venerating him as son of Allah. The misconception has also taken hold of a sect of the Muslims. They have invented the belief that Prophet Muhammad [SAWW](PBUH) is "Light from the Light of Allah". Thus further considering to be of him with Divine qualities. They exclude him from the category of men.
