(9, 10) “Allah has promised those who believe and do righteous deeds that they will have forgiveness and a tremendous reward.”

That is, Allah—who never breaks His promise and is the truest of speakers—has promised those who believe in Him, His Books, His messengers, and the Last Day, and who perform righteous deeds, both obligatory and recommended, forgiveness for their sins by pardoning them and their consequences, as well as a tremendous reward whose greatness is known only to Allah Most High.

“No soul knows what delights of the eyes have been kept hidden for them as a reward for what they used to do.”
