Surah At-Tur (The Mount): Verse 18

And His saying, {rejoicing} (fākihīn): This adds to the description, because a person enjoying blessings might only show the enjoyment outwardly while his heart is preoccupied. When He says, {rejoicing}, it indicates the utmost delight.

And His saying, {in what their Lord has given them}: This conveys an increase in that state. This is because a person of base character might be delighted by the slightest thing and rejoice over the smallest cause. Thus, He says they are {rejoicing}, not because of the lowness of their aspirations, but because of the loftiness of their blessings, as they are from their Lord.

And His saying, the Exalted, {and their Lord protected them from the punishment of the Hellfire}: This carries two possibilities:

1. That the meaning is that they are rejoicing in two matters: one is what their Lord has given them, and the other is that their Lord protected them.
2. That this is a separate clause connected to the first one, as if He is clarifying that He admitted them into Gardens and bliss, and protected them from the punishment of the Hellfire.
