On the Day when some faces will be (lit up with) white, and some faces will be (in the gloom of) black: To those whose faces will be black, (will be said): “Did ye reject Faith after accepting it? Taste then the penalty for rejecting Faith.”
Aswadah means, “clouded” or “his face became
expressive of grief or sorrow” (Râghib, Tâj). It is an expression for an
unsatisfactory or undesirable condition, failure, or sorrow (Lisân; see
also 75:23; 80:39).
