وَيا قَومِ اعمَلوا عَلىٰ مَكانَتِكُم إِنّي عامِلٌ ۖ سَوفَ تَعلَمونَ مَن يَأتيهِ عَذابٌ يُخزيهِ وَمَن هُوَ كاذِبٌ ۖ وَارتَقِبوا إِنّي مَعَكُم رَقيبٌ

And O my people, work according to your position; indeed, I am working. You are going to know to whom will come a punishment that will disgrace him and who is a liar. So watch; indeed, I am with you a watcher, [awaiting the outcome]."
