﴿ وَيَٰقَوْمِ ٱعْمَلُوا۟ عَلَىٰ مَكَانَتِكُمْ إِنِّى عَٰمِلٌۭ ۖ سَوْفَ تَعْلَمُونَ مَن يَأْتِيهِ عَذَابٌۭ يُخْزِيهِ وَمَنْ هُوَ كَٰذِبٌۭ ۖ وَٱرْتَقِبُوٓا۟ إِنِّى مَعَكُمْ رَقِيبٌۭ ﴾

“Hence, O my people, do [to me] anything that may be within your power, [while] I, behold, shall labour [in God's way]; in time you will come to know which [of us] shall be visited by suffering that will cover him with ignominy, and which [of us] is a liar. Watch, then, [for what is coming:] behold, I shall watch with you!"”

And O my people act according to your ability your circumstances lo! I too am acting according to mine. You will soon know upon whom man is the relative particle introducing the direct object of the action of ‘knowing’ will come the chastisement that will abase him and who is a liar. And sit in watch wait for the consequence of your affair I too will be with you watching’ waiting.
