Surah At-Tur, Verse 47

وَإِنَّ لِلَّذِينَ ظَلَمُواْ عَذَابٗا دُونَ ذَٰلِكَ وَلَٰكِنَّ أَكۡثَرَهُمۡ لَا يَعۡلَمُونَ٤٧

wa-inna lilladhīna ẓalamū ʿadhāban dūna dhālika walākinna aktharahum lā yaʿlamūna

And indeed, for those who have wronged is a punishment before that, but most of them do not know.
