COMMENTARY on 68:43
A. Yusuf Ali:

Translation:
Their eyes will be 5623 cast down,- ignominy will cover them; seeing that they had been summoned aforetime to prostate in adoration, while they were in good shape, 5624 (and had refused).
Commentary:

5623  Their past memories, combined with their present position, will then fill them with a sense of the deepest dismay and humiliation. See last note.

5624  Salimun: whole, in full possession of the power of judgement and will; not constrained, as they now will be, by the Punishment staring them full in the face.
