Al Muminun, 77 Ayah
23:77
حَتَّىٰٓ إِذَا فَتَحۡنَا عَلَيۡهِم بَابٗا ذَا عَذَابٖ شَدِيدٍ إِذَا هُمۡ فِيهِ مُبۡلِسُونَ ٧٧
Ĥattá 'Idhā Fataĥnā `Alayhim Bābāan Dhā `Adhābin Shadīdin 'Idhā Hum Fīhi Mublisūna
Until when We have opened before them a door of severe punishment, immediately they will be therein in despair.
