What is the preponderant opinion regarding the intended meaning of "wisdom" in His Almighty's saying, "And Allah has sent down upon you the Book and wisdom," is it the knowledge of the secrets of Islamic law or the Prophetic Sunnah, taking into consideration Ibn Uthaymeen's preference?

The interpretation of "wisdom" mentioned in the verse: (And Allah has revealed to you the Book and Wisdom) is the Sunnah. Ibn Uthaymeen, in several places in his books, indicated that wisdom is the Sunnah, and that it clarifies the Qur'an. He also indicated that the Sunnah is a divine revelation like the Qur'an. Ibn Uthaymeen mentioned the possibility that wisdom could be the secrets of Islamic law, but this is less probable compared to interpreting it as the Sunnah. What is well-known among the early exegetes is the interpretation of wisdom as the Sunnah.
