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

(11) And if you divorce them before you have touched (had a sexual relation with) them, and you have appointed unto them the Mahr (bridal-money given by the husband to his wife at the time of marriage), then pay half of that (Mahr), unless they (the women) agree to forego it, or he (the husband), in whose hands is the marriage tie, agrees to forego and give her full appointed Mahr. And to forego and give (her the full Mahr) is nearer to At-Taqwa (piety, righteousness). And do not forget liberality between yourselves. Truly, Allah is All-Seer of what you do.

(12) Truly those who believe, and do deeds of righteousness, and perform As-Salat (Iqamat-as-Salat), and give Zakat they will have their reward with their Lord. On them shall be no fear, nor shall they grieve.

(13) Then the angels called him, while he was standing in prayer in Al-Mihrab (a praying place or a private room), (saying): "Allah gives you glad tidings of Yahya (John), confirming (believing in) the word from Allah [i.e. the creation of 'Îsa (Jesus) عليه السلام, the Word from Allah ("Be!" - and he was!)], noble, keeping away from sexual relations with women, a Prophet, from among the righteous."

(14) "He will speak to the people in the cradle and in manhood, and he will be one of the righteous."

(15) And as for those who believe (in the Oneness of Allah) and do righteous good deeds, Allah will pay them their reward in full. And Allah does not like the Zalimun (polytheists and wrong-doers).

(16) Except for those who repent after that and do righteous deeds. Verily, Allah is Oft-Forgiving, Most Merciful.

(17) By no means shall you attain Al-Birr (piety, righteousness - here it means Allah's Reward, i.e. Paradise), unless you spend (in Allah's Cause) of that which you love; and whatever of good you spend, Allah knows it well.

(18) They believe in Allah and the Last Day; they enjoin Al-Ma'ruf (Islamic Monotheism, and following Prophet Muhammad صلى الله عليه وسلم) and forbid Al-Munkar (polytheism, disbelief and opposing Prophet Muhammad صلى الله عليه وسلم); and they hasten in (all) good works; and they are among the righteous.

(19) For such, the reward is Forgiveness from their Lord, and Gardens with rivers flowing underneath (Paradise), wherein they shall abide forever. How excellent is this reward for the doers (who do righteous deeds according to Allah's Orders).

(20) "Our Lord! Verily, we have heard the call of one (Muhammad صلى الله عليه وسلم) calling to Faith: 'Believe in your Lord,' and we have believed. Our Lord! Forgive us our sins and expiate from us our evil deeds, and make us die (in the state of righteousness) along with Al-Abrar (the pious believers of Islamic Monotheism).
