Surah Taha 20:15

إِنَّ ٱلسَّاعَةَ ءَاتِيَةٌ أَكَادُ أُخْفِيهَا لِتُجْزَىٰ كُلُّ نَفْسٍۭ بِمَا تَسْعَىٰ

Indeed, the Hour is coming - I almost conceal it - so that every soul may be recompensed according to that for which it strives.

Translation: Saheeh International

Tafsir

The Hour is assuredly coming. But I will to keep it hidden from mankind — and its nearness in time will manifest itself to them through its signs — so that every soul may be requited thereupon for what it strives for of good or evil.
