Translation:

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

Notes (Tafseer)

5949. Cf. x. 45, where the expression used is: "it will be as if they had tarried but an hour of a day." Here the metaphor used is "a single evening, or, at most, till the following morn". Death is like sleep, and may be compared to the evening of life. In sleep we do not know how the time passes. When we wake up from the sleep of Death at the Resurrection, we shall not know whether it was the following moment or the following hour after we slept, but we shall feel that it is morning, for we shall be conscious of all that goes on, as one awakened in the morning.
