حَتَّىٰٓ إِذَا فَتَحْ نَا عَلَيْ هِم بَابًا ذَا عَذَابٍ شَدِيدٍ إِذَا هُمْ فِي هِ مُبْلِسُونَ
Until when We have opened before them a door of severe punishment, immediately they will be therein in despair.

وَ إِن كَانُ وا۟ مِن قَبْلِ أَن يُنَزَّلَ عَلَيْ هِم مِّن قَبْلِ هِۦ لَ مُبْلِسِينَ
Although they were, before it was sent down upon them - before that, in despair.

لَا يُفَتَّرُ عَنْ هُمْ وَ هُمْ فِي هِ مُبْلِسُونَ

فَ لَمَّا نَسُ وا۟ مَا ذُكِّرُ وا۟ بِ هِۦ فَتَحْ نَا عَلَيْ هِمْ أَبْوَٰبَ كُلِّ شَىْءٍ حَتَّىٰٓ إِذَا فَرِحُ وا۟ بِ مَآ أُوتُ وٓا۟ أَخَذْ نَٰ هُم بَغْتَةً فَ إِذَا هُم مُّبْلِسُونَ
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.
