Certainly did Allāh confer [great] favor upon the believers when He sent among them a Messenger from themselves, reciting to them His verses and purifying them and teaching them the Book [i.e., the Qur’ān] and wisdom, although they had been before in manifest error.

Allah has surely conferred favor on the believers when He raised in their midst a messenger from among themselves who recites to them His verses and makes them pure and teaches them the Book and the Wisdom, while earlier, they were in open error.
