The word(s) "righteous" appears 184 time(s) in 178 verse(s) in Quran in Mohsin Khan translation.

(121) And those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds, to them We shall surely give lofty dwellings in Paradise, underneath which rivers flow, to live therein forever. Excellent is the reward for the workers.

(122) Then as for those who believed (in the Oneness of Allah - Islamic Monotheism) and did righteous good deeds, such shall be honoured and made to enjoy luxurious life (forever) in a Garden of Delight (Paradise).

(123) Whosoever disbelieves will suffer from his disbelief, and whosoever does righteous good deeds (by practising Islamic Monotheism), then such will prepare a good place (in Paradise) for themselves (and will be saved by Allah from His Torment).

(124) That He may reward those who believe (in the Oneness of Allah - Islamic Monotheism), and do righteous good deeds, out of His Bounty. Verily, He likes not the disbelievers.

(125) So on that Day no excuse of theirs will avail those who did wrong (by associating partners in worship with Allah, and by denying the Day of Resurrection), nor will they be allowed (then) to return to seek Allah's Pleasure (by having Islamic Faith with righteous deeds and by giving up polytheism, sins and crimes with repentance).

(126) Verily, those who believe (in Islamic Monotheism) and do righteous good deeds, for them are Gardens of Delight (Paradise).

(127) See you not (O men) that Allah has subjected for you whatsoever is in the heavens and whatsoever is in the earth, and has completed and perfected His Graces upon you, (both) apparent (i.e. Islamic Monotheism, and the lawful pleasures of this world, including health, good looks, etc.) and hidden [i.e. One's Faith in Allah (of Islamic Monotheism) knowledge, wisdom, guidance for doing righteous deeds, and also the pleasures and delights of the Hereafter in Paradise]? Yet of mankind is he who disputes about Allah without knowledge or guidance or a Book giving light!

(128) And if you only could see when the Mujrimun (criminals, disbelievers, polytheists, sinners) shall hang their heads before their Lord (saying): "Our Lord! We have now seen and heard, so send us back (to the world), that we will do righteous good deeds. Verily! We now believe with certainty."

(129) As for those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds, for them are Gardens (Paradise) as an entertainment for what they used to do.

(130) And whosoever of you is obedient to Allah and His Messenger (صلى الله عليه وسلم), and does righteous good deeds, We shall give her, her reward twice over, and We have prepared for her Rizq Karim (a noble provision - Paradise).
