حَتَّىٰ إِذَا فَتَحْنَا عَلَيْهِم بَابًا ذَا عَذَابٍ شَدِيدٍ إِذَا هُمْ فِيهِ مُبْلِسُونَ
Hatta itha fatahna AAalayhim baban tha AAathabin shadeedin itha hum feehi mublisoona
Until when We opened for them a gate of a punishment severe, behold! They in it (will be in) despair.
until We open before them a gate of [truly] severe suffering [in the life to come]: and then, lo! they will be broken in spirit.
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.
Until, when We open for them a door of severe chastisement, lo! they are in despair at it.
Until when We have opened before them a door of severe punishment, immediately they will be therein in despair.
