In this surah, thirteen ayahs begin either with a conjunction and anna (as in the first reading here), or with inna (emphatic particle) to create a new sentence. At this particular juncture, arguably beyond the earlier passage, several Readers switch from their usual inna to recite with anna. Note: all Reciters have fathah in ayahs 16 and 18.
He has revealed to you ˹O Prophet˺ the Book in truth, confirming what came before it, as He revealed the Torah and the Gospel
