The Meaning of the Saying of Allah the Exalted: "And the Clear Book."

The Shaykh : The waw here is for the oath, and the intended meaning of "the Clear Book" is the Noble Qur'an. It is called a "book" because it is written in the Preserved Tablet, because it is written in the scrolls in the hands of the angels, and because it is written in the scrolls in our hands. Therefore, the form fa'alan here means maf'ul (passive participle). The Arabic language comes—... in a specific way, and in short, sometimes it is long and sometimes it is short, and this does not fit—here "book" means "written," just as "ghiras" means "planted" and "bina'" means "built," and the like. Is the intended meaning of "al-Mubin" (the Clear) that it is clear in itself, or that it is clear to others, or is the intended meaning both of these? The answer is that the intended meaning is both of these, based on a rule we mentioned to you in the first lesson. We mentioned it in the first lesson we delivered here. What is the rule in tafsir (exegesis) that we mentioned? Please.

The Shaykh :"And there is no contradiction between them, nor is one of them stronger than the other. This condition is necessary. May Allah reward you."
