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

(131) He will direct you to do righteous good deeds and will forgive you your sins. And whosoever obeys Allah and His Messenger (صلى الله عليه وسلم), he has indeed achieved a great achievement (i.e. he will be saved from the Hell-fire and will be admitted to Paradise).

(132) That He may recompense those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds. Those, theirs is forgiveness and Rizq Karim (generous provision, i.e. Paradise).

(133) Saying: "Make you perfect coats of mail, and balance well the rings of chain armour, and work you (men) righteousness. Truly, I am All-Seer of what you do."

(134) And it is not your wealth, nor your children that bring you nearer to Us (i.e. please Allah), but only he who believes (in the Islamic Monotheism), and does righteous deeds (will please Us); as for such, there will be twofold reward for what they did, and they will reside in the high dwellings (Paradise) in peace and security.

(135) So Today (i.e. the Day of Resurrection), none of you can profit or harm one another. And We shall say to those who did wrong [i.e. worshipped others (like the angels, jinn, prophets, saints, righteous persons) along with Allah]: "Taste the torment of the Fire which you used to belie.

(136) Those who disbelieve, theirs will be a severe torment; and those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds, theirs will be forgiveness and a great reward (i.e. Paradise).

(137) Whosoever desires honour, (power and glory), then to Allah belong all honour, power and glory [and one can get honour, power and glory only by obeying and worshipping Allah (Alone)]. To Him ascend (all) the goodly words, and the righteous deeds exalt it (i.e. the goodly words are not accepted by Allah unless and until they are followed by good deeds), but those who plot evils, theirs will be severe torment. And the plotting of such will perish.

(138) Therein they will cry: "Our Lord! Bring us out, we shall do righteous good deeds, not (the evil deeds) that we used to do." (Allah will reply): "Did We not give you lives long enough, so that whosoever would receive admonition could receive it? And the warner came to you. So taste you (the evil of your deeds). For the Zalimun (polytheists and wrong-doers) there is no helper."

(139) And when it is said to them: "Fear of that which is before you (worldly torments), and that which is behind you (torments in the Hereafter), in order that you may receive Mercy (i.e. if you believe in Allah's religion - Islamic Monotheism, and avoid polytheism, and obey Allah with righteous deeds)."

(140) "My Lord! Grant me (offspring) from the righteous."
