Quran 33:63 Al-Ahzab, ayah 63 of 73

يَسْـَٔلُكَ ٱلنَّاسُ عَنِ ٱلسَّاعَةِ ۖ قُلْ إِنَّمَا عِلْمُهَا عِندَ ٱللَّهِ ۚ وَمَا يُدْرِيكَ لَعَلَّ ٱلسَّاعَةَ تَكُونُ قَرِيبًا ۝٦٣

33:63 Men ask thee of the Hour. Say: The knowledge of it is with Allah only. What can convey (the knowledge) unto thee? It may be that the Hour is nigh.
