Verse 187

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

They ask you about the Hour and when it will come to pass. Say; indeed its knowledge is with my Lord. No one reveals its time except Him. Heavy it is indeed in the vacua and matter. It will not come to pass except suddenly. They ask you as though you know about it. Say; indeed its knowledge is with God, however, most people do not know.
