فَلَمَّا So when نَسُوا۟ they forgot مَا what ذُكِّرُوا۟ they were reminded بِهِۦ of [it] فَتَحْنَا We opened عَلَيْهِمْ on them أَبْوَٰبَ gates كُلِّ (of) every شَىْءٍ thing حَتَّىٰٓ until إِذَا when فَرِحُوا۟ they rejoiced بِمَآ in what أُوتُوٓا۟ they were given أَخَذْنَـٰهُم We seized them بَغْتَةًۭ suddenly فَإِذَا and then هُم they مُّبْلِسُونَ (were) dumbfounded ٤٤
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.
