Quran 52:47
For these wrongdoers, there is another punishment [30] besides this, but most of them know it not. (52:47) [30] This is a reference to the punishment which, before the Day of Judgement, in accordance with the established practice of God visits people who persist in denying the truth even after it has been conclusively communicated to them by messengers of God. Ghamidi Sahab commentary from Al-Bayan. Yes, it is talking about the Azaab given right after Itmam-e-Hujjat.
