وَيَٰقَوْمِ ٱعْمَلُوا۟ عَلَىٰ مَكَانَتِكُمْ إِنِّى عَٰمِلٌ ۖ سَوْفَ تَعْلَمُونَ مَن يَأْتِيهِ عَذَابٌ يُخْزِيهِ وَمَنْ هُوَ كَٰذِبٌ ۖ وَٱرْتَقِبُوٓا۟ إِنِّى مَعَكُمْ رَقِيبٌ

And, O my people! act according to your ability, I too am acting; you will come to know soon who it is on whom will light the punishment that will disgrace him and who it is that is a liar, and watch, surely I too am watching with you.
