The word(s) "worker" appears 6 time(s) in 6 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) So their Lord accepted their prayer: That I will not waste the work of a worker among you, whether male or female, the one of you being from the other; they, therefore, who fled and were turned out of their homes and persecuted in My way and who fought and were slain, I will most certainly cover their evil deeds, and I will most certainly make them enter gardens beneath which rivers flow; a reward from Allah, and with Allah is yet better reward.

(2) He said: That in which my Lord has established me is better, therefore you only help me with workers, I will make a fortified barrier between you and them;

(3) And (as for) those who believe and do good, We will certainly give them abode in the high places in gardens beneath which rivers flow, abiding therein; how good the reward of the workers:

(4) For the like of this then let the workers work.

(5) Say: O my people! work in your place, surely I am a worker, so you will come to know.

(6) And they shall say: (All) praise is due to Allah, Who has made good to us His promise, and He has made us inherit the land; we may abide in the garden where we please; so goodly is the reward of the workers.
