وَيَا قَوْمِ اعْمَلُوا عَلَىٰ مَكَانَتِكُمْ إِنِّي عَامِلٌ ۖ سَوْفَ تَعْلَمُونَ مَنْ يَأْتِيهِ عَذَابٌ يُخْزِيهِ وَمَنْ هُوَ كَاذِبٌ ۖ وَارْتَقِبُوا إِنِّي مَعَكُمْ رَقِيبٌ 93
"And O my people! Do whatever ye can: I will do (my part): Soon will ye know who it is on whom descends the penalty of ignominy; and who is a liar! and watch ye! for I too am watching with you!"
