Surah 39. Az-Zumar, Ayah 24

Lit., "who will protect himself with his face": an idiomatic phrase implying that the person concerned has nothing whatever with which to protect himself.

The unrepentant Sinners will receive the full Penalty on the Day of Judgment. They will receive it full in the face, i.e., their whole being will be affected by it. Their hands will be tied, and they cannot therefore use their hands to ward off the Penalty of the Fire: in any case their hands will not have the power to ward it off. Are such helpless people to be compared for a moment with people who have received Grace and are therefore guarded from all harm and danger? Certainly not. To the evil the fruit of their deed, and to the good the grace of their Lord!

That is, of all their misdeeds, all the evil which they did in the world.
