And when he mentioned the lesson, he mentioned the subject of the lesson. So Allah, the Most High, said: "Indeed, for you"; meaning specifically, in a manner of emphasis that there is no allowance for neglecting it. "In it"; meaning the Book, so that you may be in the utmost trust in it, not in anything else in which you have no trust. "What you choose"; meaning you exaggerate in selecting it and taking its choice. He broke the hamzah, and its rightful form would have been with a fathah were it not for the lam, because what follows it is the subject of the lesson. It is permissible that the sentence be a narration of the subject of the lesson and that it be an independent statement.
