Quran 33:63 — The Parties (Al-Ahzab)

يَسـَٔلُكَ النّاسُ عَنِ السّاعَةِ ۖ قُل إِنَّما عِلمُها عِندَ اللَّهِ ۚ وَما يُدريكَ لَعَلَّ السّاعَةَ تَكونُ قَريبًا

The people ask you about the Hour (end of the world). Say, "The knowledge thereof is only with GOD. For all that you know, the Hour may be close."

[33:62] This is GOD's eternal system, and you will find that GOD's system is unchangeable.

[33:64] GOD has condemned the disbelievers, and has prepared for them Hell.
