حَتَّى إِذَا فَتَحْنَا عَلَيْهِم بَابًا ذَا عَذَابٍ شَدِيدٍ إِذَا هُمْ فِيهِ مُبْلِسُونَ
[23:77]
Until when We open upon them a door of severe chastisement, lo! they are in despair at it.
Until We open on them a gate leading to a severe Punishment: then Lo! they will be plunged in despair therein!
Until, when We open for them the gate of extreme punishment, behold! they are aghast thereat.
