Surely the righteous will be in bliss,

and the sinners in Hell,

in which they will enter on the Day of Requital,

and they will not (be able to) keep away from it.

And what may let you know what the Day of Requital is?

Again, what may let you know what the Day of Requital is?

A Day when no one will have power to do any thing for another! And command, on that Day, will belong to Allah (alone).
