يَسأَلونَكَ عَنِ السّاعَةِ أَيّانَ مُرساها ۖ قُل إِنَّما عِلمُها عِندَ رَبّي ۖ لا يُجَلّيها لِوَقتِها إِلّا هُوَ ۚ ثَقُلَت فِي السَّماواتِ وَالأَرضِ ۚ لا تَأتيكُم إِلّا بَغتَةً ۗ يَسأَلونَكَ كَأَنَّكَ حَفِيٌّ عَنها ۖ قُل إِنَّما عِلمُها عِندَ اللَّهِ وَلـٰكِنَّ أَكثَرَ النّاسِ لا يَعلَمونَ

They ask you, [O Muhammad], about the Hour: when is its arrival? Say, "Its knowledge is only with my Lord. None will reveal its time except Him. It lays heavily upon the heavens and the earth. It will not come upon you except unexpectedly." They ask you as if you are familiar with it. Say, "Its knowledge is only with Allah, but most of the people do not know."
