فَلَمَّا نَسُوا مَا ذُكِّرُوا بِهِۦ فَتَحْنَا عَلَيْهِمْ أَبْوَٰبَ كُلِّ شَىْءٍ حَتَّىٰٓ إِذَا فَرِحُوا بِمَآ أُوتُوٓا أَخَذْنَـٰهُم بَغْتَةً فَإِذَا هُم مُّبْلِسُونَ

Falamma nasoo ma thukkiroobihi fatahna AAalayhim abwaba kulli shay-in hattaitha farihoo bima ootoo akhathnahumbaghtatan fa-itha hum mublisoon

So when they forgot that by which they had been reminded, We opened to them the doors of every [good] thing until, when they rejoiced in that which they were given, We seized them suddenly, and they were [then] in despair.
