الاعراف — Al-A'raf Ayat 187
يَسْـَٔلُوْنَكَ عَنِ السَّاعَةِ اَيَّانَ مُرْسٰىهَاۗ قُلْ اِنَّمَا عِلْمُهَا عِنْدَ رَبِّيْۚ لَا يُجَلِّيْهَا لِوَقْتِهَآ اِلَّا هُوَۘ ثَقُلَتْ فِى السَّمٰوٰتِ وَالْاَرْضِۗ لَا تَأْتِيْكُمْ اِلَّا بَغْتَةً ۗيَسْـَٔلُوْنَكَ كَاَنَّكَ حَفِيٌّ عَنْهَاۗ قُلْ اِنَّمَا عِلْمُهَا عِنْدَ اللّٰهِ وَلٰكِنَّ اَكْثَرَ النَّاسِ لَا يَعْلَمُوْنَ

"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.""
