ب-ل-س

فَلَمَّا نَسُوا۟ مَا ذُكِّرُوا۟ بِهِۦ فَتَحْنَا عَلَيْهِمْ أَبْوَٰبَ كُلِّ شَىْءٍ حَتَّىٰٓ إِذَا فَرِحُوا۟ بِمَآ أُوتُوٓا۟ أَخَذْنَـٰهُم بَغْتَةً فَإِذَا هُم مُّبْلِسُونَ

So when they forgot that by which they had been reminded,1 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.

حَتَّىٰٓ إِذَا فَتَحْنَا عَلَيْهِم بَابًا ذَا عَذَابٍ شَدِيدٍ إِذَا هُمْ فِيهِ مُبْلِسُونَ

Until when We have opened before them a door of severe punishment, immediately they will be therein in despair.

وَيَوْمَ تَقُومُ ٱلسَّاعَةُ يُبْلِسُ ٱلْمُجْرِمُونَ

And the Day the Hour appears the criminals will be in despair.

وَإِن كَانُوا۟ مِن قَبْلِ أَن يُنَزَّلَ عَلَيْهِم مِّن قَبْلِهِۦ لَمُبْلِسِينَ

Although they were, before it was sent down upon them - before that, in despair.

لَا يُفَتَّرُ عَنْهُمْ وَهُمْ فِيهِ مُبْلِسُونَ

It will not be allowed to subside for them, and they, therein, are in despair.
