فَلَا تَضْرِبُوا۟ لِلَّهِ ٱلْأَمْثَالَ ۚ إِنَّ ٱللَّهَ يَعْلَمُ وَأَنتُمْ لَا تَعْلَمُونَ
Commentary:
The verse means to say that it is foolish on the part of man to devise a law regarding God Himself while he is quite ignorant of His unlimited powers. God has reserved to Himself the right to grant to His servants such privileges in respect of religion as He in His infinite, infallible wisdom regards suitable and for this purpose He chooses him whom He considers really deserving, on account of his sincerity and devotion, to be raised to the rank of His spiritual heir.
In some Scriptures some of the Prophets have been called "sons of God". Such expressions have been used metaphorically and only mean that God chose them to be the heirs to His heavenly kingdom. But men out of their ignorance and perversity take such expressions literally and begin to regard God’s honoured servants as His sons in the physical sense of the word. By applying to them the epithet "the sons of God", these Divine Scriptures meant to demonstrate their spiritual eminence and very deep connection with Him. It is foolish to read in such terms any significance unworthy of God.
The words, Allah knows and you know not, signify that such expressions when used in heavenly Scriptures do not conflict with God’s attributes. For example, the epithet "son" when used by God about a person means one who has such close spiritual connection with Him as is possessed by a son with his parents. But when disbelievers use this term, they use it in its physical sense and thus detract, on the one hand, from the Supreme Exaltedness of God and, on the other, from the dignity of those whom in their folly they wish to honour; because a physical relationship cannot equal the honour and dignity which result from spiritual nearness to God.
It is highly presumptuous on the part of man to devise a law regarding God while he is quite ignorant of His great and unlimited powers.
