وَيَا قَوْمِ اعْمَلُوا عَلَىٰ مَكَانَتِكُمْ إِنِّي عَامِلٌ ۖ سَوْفَ تَعْلَمُونَ مَن يَأْتِيهِ عَذَابٌ يُخْزِيهِ وَمَنْ هُوَ كَاذِبٌ ۖ وَارْتَقِبُوا إِنِّي مَعَكُمْ رَقِيبٌ (93)
(11:93) My people! Go on working according to your way and I will keep working (according to mine). Soon you will come to know who will be afflicted by a humiliating chastisement, and who is proved a liar. And watch, I shall also watch with you.'
