Surah Al-'Ankabut, ayah 53

29:53

وَيَسۡتَعۡجِلُونَكَ بِٱلۡعَذَابِ وَلَوۡلَآ أَجَلٞ مُّسَمّٗى لَّجَآءَهُمُ ٱلۡعَذَابُۚ وَلَيَأۡتِيَنَّهُم بَغۡتَةٗ وَهُمۡ لَا يَشۡعُرُونَ ٥٣

Wayasta'jilūnaka bil-'adhābi walawlā ajalum musammal lajā'ahumul-'adhābu walaya'tiyannahum baghtatan wahum lā yash'urūn

And they urge you to hasten the punishment. And if not for [the decree of] a specified term, punishment would have reached them. But it will surely come to them suddenly while they perceive not.
