On the Day when they behold it, [it will seem to them] as if they had tarried [in this world] no longer than one evening or [one night, ending with] its morn!

The Day they see it, (It will be) as if they had tarried but a single evening, or (at most till) the following morn!

On the day when they behold it, it will be as if they had but tarried for an evening or the morn thereof.

On the day when they see it, it will be as if they had but tarried for an evening or a morning.

It will be, on the Day they see it, as though they had not remained [in the world] except for an afternoon or a morning thereof.
