Surah 52. At-Tur, Ayah 16

I.e., "you will have to endure it in either case, for it is but a consequence of your own doings and attitudes": a subtle allusion to the fact that the "punishments" and "rewards" in the life to come are but allegories of the logical consequences of the manner in which one acts or behaves in this life.

 One gets the reward for being patient in difficult times in this world. As for the Hereafter, those who suffer patiently in Hell will not be rewarded for their patience.

At that stage they will have no justification for anger or impatience; for their whole position will have been due to their own conduct and their rejection of Allah's Grace. Nor will there be time then for patience or repentance, for their period of probation will then have been over.
