Surah Al-Ahzab 33:63

يَسْـَٔلُكَ ٱلنَّاسُ عَنِ ٱلسَّاعَةِ ۖ قُلْ إِنَّمَا عِلْمُهَا عِندَ ٱللَّهِ ۚ وَمَا يُدْرِيكَ لَعَلَّ ٱلسَّاعَةَ تَكُونُ قَرِيبًا

People ask you concerning the Hour. Say, "Knowledge of it is only with Allāh. And what may make you perceive? Perhaps the Hour is near."

Translation: Saheeh International

Tafsir

People such as the people of Mecca question you concerning the Hour when will it be? Say ‘Knowledge thereof lies only with God — and what do you know what would provide you with knowledge thereof? In other words you do not know it perhaps the Hour is near’.
