These readings provide complementary meanings: the Prophet ﷺ is to be trusted in what he conveys from the Unseen, and he passes on everything with integrity and clarity [Makki]. NB: the standard codices all have ḍād as in the first reading, so the ẓā' reading accords with that script due to the similarity of the two letters.
He has revealed to you ˹O Prophet˺ the Book in truth, confirming what came before it, as He revealed the Torah and the Gospel
