Translation:

57. As a Bounty from thy Lord! That will be the supreme achievement!

Notes (Tafseer)

4733. This is our idea of Salvation; the negative avoidance of all the consequences of evil, and the positive attainment of all-and more than all-that our hearts could possibly desire. For Allah's Bounty outstrips anything that our eyes have seen, or our ears have heard of, or our imagination can conceive.
