Surah 10. Yunus, Ayah 45

I.e., their past sojourn in this world, during which they were bound to one another by various ties of human relationship, will appear to them like a short moment as compared with the timeless duration of the life that awaits them after resurrection (see note [19] on {79:46), with all their past relationships cut asunder. See also 6:94 , which describes the condition of the deniers of the truth on the Day of Resurrection: "And now, indeed, you have come unto Us in a lonely state, even as We created you in the first instance"; and later on, in that same verse: "Indeed, all the bonds between you [and your earthly life] are now severed...."

 i.e., only for a short period of time.

In eternity our life on this earth will look as if it had been just a little part of our little day, and so also will appear any interval between our death and the call to Judgment.

We shall retain some perception of our mutual relations on earth, so that the righteous judgment which will be pronounced will be intelligible to us, and we shall be convinced of its righteousness.
