The Holy Quran 54:49 — Surah Al-Qamar
Arabic text
إِنَّا كُلَّ شَىْءٍ خَلَقْنَـٰهُ بِقَدَرٍ
Translation
We have certainly created everything by (finely calculated) measure (so that everything meets the requirements for its task and so that everything happens when it is destined to happen).
Tafsir (excerpt) — Tafsir Usmani
That is, everything that is to happen has been fixed beforehand in Allah’s knowledge. The lifespan of the world and the time of the Hour are also fixed in His knowledge; it cannot come sooner or later than that.
