﴾30﴿ And the Jews say that Uzair (peace be upon him) is the son of Allah Almighty, and the Christians say that the Messiah (peace be upon him) (Jesus) is the son of Allah Almighty This is their saying, they imitate with their mouths (i.e. without reason) the saying of those who disbelieved before them May Allah Almighty curse them. How can they deviate from the truth
﴾31﴿ They have made their scholars and preceptor the authorities (of what is lawful and what is forbidden) except from Allah Almighty and the Messiah, son of Mary but, it has not been decreed upon them except that you should make worship exclusive to the One Helper. there is not worthy of worship other than Him. His purity is above what they associate with Him

[30] In this verse, four other reasons for fighting them are mentioned. The polytheism of the Jews was that they said Ezra (peace be upon him) is the son of Allah, and the polytheism of the Christians was that they said Jesus (peace be upon him) is the son of Allah.
The belief of the common people in this was that they are truly the sons of Allah, the Exalted.
And the belief of the elite was that they are like favored sons in the sight of Allah, the Exalted—whose word is accepted by the Father and who are granted authority.
Both of these beliefs are disbelief (kufr).
Among the ignorant ones of this Ummah, the second belief is widely found.
(“Their words with their mouths”) refers to their baseless statements.
(“Like the words of those who disbelieved before”) refers to those disbelieving pagans who used to say the angels are the daughters of Allah, the Exalted, or it refers to their leaders whom they imitated in disbelief.
(“May Allah destroy them”)—this is an evil supplication (a curse), and what is meant by it is a curse.
[31] In this verse, other reasons for fighting are mentioned.
(“Their rabbis”) refers to those scholars who present the words and meanings in a refined manner, and (“their monks”) refers to those who fear Allah, the Exalted, and devote their time and actions solely for Allah, the Exalted.
However, in this verse, since they were attributed to them (i.e., “their rabbis” and “their monks”), it indicates that they were corrupt scholars and corrupt spiritual leaders who made polytheism, disbelief, and innovations seem good to the people and said, “This is religion.”
(“As lords”)—it does not mean that they considered the scholars and spiritual leaders as actual gods, nor did they worship them.
Rather, what is meant is that if those leaders made something forbidden lawful for them, they would consider it lawful, and if they made something lawful forbidden, they would consider it forbidden—just as it is mentioned in the hadith of ʿAdiyy ibn Ḥātim (may Allah be pleased with him), which is narrated by Tirmidhi.
From this, it becomes clear that blindly following scholars and spiritual leaders in opposition to divine law is a form of shirk (associating partners with Allah).
(“And the Messiah, son of Mary”)—he is mentioned separately because he was made a partner with Allah, the Exalted, purely in worship, not merely in obedience. In fact, they had abandoned following him altogether.
This is shirk in divinity (ulūhiyyah), and both types of shirk are also present among the ignorant of this Ummah.
