The word(s) "worked" appears 4 time(s) in 4 verse(s) in Quran in Mohsin Khan translation.

(1) Surely, those who believe (in the Oneness of Allah, in His Messenger Muhammad صلى الله عليه وسلم and all that was revealed to him from Allah), and those who are the Jews and the Sabians and the Christians, - whosoever believed in Allah and the Last Day, and worked righteousness, on them shall be no fear, nor shall they grieve.

(2) But those who believed (in the Oneness of Allah - Islamic Monotheism), and worked righteousness - We tax not any person beyond his scope - such are the dwellers of Paradise. They will abide therein.

(3) And to Solomon (We subjected) the wind, its morning (stride from sunrise till midnoon) was a month's (journey), and its afternoon (stride from the midday decline of the sun to sunset) was a month's (journey i.e. in one day he could travel two months' (journey). And We caused a fount of (molten) brass to flow for him, and there were jinn that worked in front of him, by the Leave of his Lord. And whosoever of them turned aside from Our Command, We shall cause him to taste of the torment of the blazing Fire.

(4) They worked for him as he desired, (making) high rooms, images, basins as large as reservoirs, and (cooking) cauldrons fixed (in their places). "Work you, O family of Dawud (David), with thanks!" But few of My slaves are grateful.
