Quran 21:40 from Surah Al-Anbiyaa on Divine Marvels.
بَلۡ تَأۡتِيهِم بَغۡتَةٗ فَتَبۡهَتُهُمۡ فَلَا يَسۡتَطِيعُونَ رَدَّهَا وَلَا هُمۡ يُنظَرُونَ
English translation: Nay it will come to them unexpectedly and bewilder them then not they will be able to repel it and not they will be given respite
Transliteration: bal tatihim baghtatan fatabhatuhum fala yastati'una raddaha wala hum yunzaruna
