Surah Hud Verse 76 - English Translation by Muhammad Mahmoud Ghali
Surah Hudيَـٰٓإِبۡرَٰهِيمُ أَعۡرِضۡ عَنۡ هَٰذَآۖ إِنَّهُۥ قَدۡ جَآءَ أَمۡرُ رَبِّكَۖ وَإِنَّهُمۡ ءَاتِيهِمۡ عَذَابٌ غَيۡرُ مَرۡدُودٖ
O Ibrahim, veer away from this. Surely your Lord's Command has already come; and surely there is coming up to them a torment not to be turned back." (i.e., without any possibility of being turned back)
