وَيَٰقَوۡمِ ٱعۡمَلُواْ عَلَىٰ مَكَانَتِكُمۡ إِنِّي عَٰمِلٞۖ سَوۡفَ تَعۡلَمُونَ مَن يَأۡتِيهِ عَذَابٞ يُخۡزِيهِ وَمَنۡ هُوَ كَٰذِبٞۖ وَٱرۡتَقِبُوٓاْ إِنِّي مَعَكُمۡ رَقِيبٞ

O my people! Act according to your ability; I too am acting. Soon you will know who will be overtaken by a punishment that will disgrace him, and who is a liar. So be on the watch; I too will be watching along with you.’
