Al-Anbya 21:104

Yawma natwee assamaakatayyi assijlli lilkutubi kama bada/naawwala khalqin nuAAeeduhu waAAdan AAalayna innakunna faAAileen

The Day when We will fold the heaven like the folding of a [written] sheet for the records. As We began the first creation, We will repeat it. [That is] a promise binding upon Us. Indeed, We will do it.

- the Day when We roll up the sky like a scroll rolls up the writings. Just as We originated the first creation, so We shall bring it back again - a promise (undertaken to be binding) on Us. We are sure to do it.
