Translation:

11. But to no soul will Allah grant respite when the time appointed (for it) has come: and Allah is well-acquainted with (all) that ye do.

Notes (Tafseer)

5478. When our limited period of probation is over, we cannot justly ask for more time, nor will more time be given to us then. Procrastination is itself a fault, and Allah knows every hidden thought and motive in our minds.
