Quran 6:44 from Surah Al-An'aam on Divine Marvels.
فَلَمَّا نَسُواْ مَا ذُكِّرُواْ بِهِۦ فَتَحۡنَا عَلَيۡهِمۡ أَبۡوَٰبَ كُلِّ شَيۡءٍ حَتَّىٰٓ إِذَا فَرِحُواْ بِمَآ أُوتُوٓاْ أَخَذۡنَٰهُم بَغۡتَةٗ فَإِذَا هُم مُّبۡلِسُونَ
English translation: So when they forgot what they were reminded of [it] We opened on them gates (of) every thing until when they rejoiced in what they were given We seized them suddenly and then they (were) dumbfounded
Transliteration: falamma nasu ma dhukkiru bihi fatahna alayhim abwaba kulli shayin hatta idha farihu bima utu akhadhnahum baghtatan fa-idha hum mub'lisuna
