Surah Al-Ankaboot, Verse 53
وَيَسْتَعْجِلُونَكَ بِٱلْعَذَابِ ۚ وَلَوْلَآ أَجَلٌۭ مُّسَمًّۭى لَّجَآءَهُمُ ٱلْعَذَابُ وَلَيَأْتِيَنَّهُم بَغْتَةًۭ وَهُمْ لَا يَشْعُرُونَ
Translation — Sahih International
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.
