Sura 33 Al-Ahzab (Those who took up arms), aya 63

1. يَسْأَلُكَ النَّاسُ عَنِ السَّاعَةِ ۖ قُلْ إِنَّمَا عِلْمُهَا عِنْدَ اللَّهِ ۚ وَمَا يُدْرِيكَ لَعَلَّ السَّاعَةَ تَكُونُ قَرِيبًا

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

   33:63
