On the day when We roll up the heavens like a scroll of books is rolled up. As We initiated the first creation, so shall We return it. It is a promise of Ours that We will do this.

[21:104] In the beginning, the entire universe was an infinitely dense small seed. At that point, there was no atom, the building block of matter, no time, and no space. Everything came into existence from a singularity, or nothingness, about 13.7 billions years ago. Verse 30 of this chapter informed us that the universe was created after a cosmic rapture, which we call the Big Bang, and now 74 verses later, we are informed about its ending, in a big crunch in reverse motion. This verse supports the model known as "closed universe." See 4:82.
