وَيَٰقَوْمِ ٱعْمَلُوا۟ عَلَىٰ مَكَانَتِكُمْ إِنِّى عَٰمِلٌۭ ۖ سَوْفَ تَعْلَمُونَ مَن يَأْتِيهِ عَذَابٌۭ يُخْزِيهِ وَمَنْ هُوَ كَٰذِبٌۭ ۖ وَٱرْتَقِبُوٓا۟ إِنِّى مَعَكُمْ رَقِيبٌۭ
And, O my people! Act according to your power, lo! I (too) am acting. Ye will soon know on whom there cometh a doom that will abase him, and who it is that lieth. And watch! Lo! I am a watcher with you.
