The word(s) "worker" appears 5 time(s) in 5 verse(s) in Quran in Saheeh International translation.

(1) Those - their reward is forgiveness from their Lord and gardens beneath which rivers flow [in Paradise], wherein they will abide eternally; and excellent is the reward of the [righteous] workers.

(2) And their Lord responded to them, "Never will I allow to be lost the work of [any] worker among you, whether male or female; you are of one another. So those who emigrated or were evicted from their homes or were harmed in My cause or fought or were killed - I will surely remove from them their misdeeds, and I will surely admit them to gardens beneath which rivers flow as reward from Allah, and Allah has with Him the best reward."

(3) And those who have believed and done righteous deeds - We will surely assign to them of Paradise [elevated] chambers beneath which rivers flow, wherein they abide eternally. Excellent is the reward of the [righteous] workers

(4) For the like of this let the workers [on earth] work.

(5) And they will say, "Praise to Allah, who has fulfilled for us His promise and made us inherit the earth [so] we may settle in Paradise wherever we will. And excellent is the reward of [righteous] workers."
