يَسْـَٔلُونَكَ عَنِ ٱلسَّاعَةِ أَيَّانَ مُرْسَىٰهَا قُلْ إِنَّمَا عِلْمُهَا عِندَ رَبِّى لَا يُجَلِّيهَا لِوَقْتِهَآ إِلَّا هُوَ ثَقُلَتْ فِى ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ لَا تَأْتِيكُمْ إِلَّا بَغْتَةً يَسْـَٔلُونَكَ كَأَنَّكَ حَفِىٌّ عَنْهَا قُلْ إِنَّمَا عِلْمُهَا عِندَ ٱللَّهِ وَلَٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يَعْلَمُونَ

It lays heavily[429] 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 Allāh, but most of the people do not know."
