The Quran

ما خَلَقنَا السَّماواتِ وَالأَرضَ وَما بَينَهُما إِلّا بِالحَقِّ وَأَجَلٍ مُسَمًّى ۚ وَالَّذينَ كَفَروا عَمّا أُنذِروا مُعرِضونَ

Muhammad Asad

We have not created the heavens and the earth and all that is between them otherwise than in accordance with [an inner] truth, and for a term set [by Us]:¹ and yet, they who are bent on denying the truth turn aside from the warning which has been conveyed unto them.²

Regarding the expression "in accordance with [an inner] truth", see note 11 on 10:5. The reference to the "term" set by God to all creation is meant to stress the fact of its finality in time as well as in space, in contrast with His Own timelessness and infinity.
Lit., "from that whereof they have been warned": i.e., they refuse to heed the warning not to attribute divine qualities to any being or force beside God.
