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

(151) You will see (on the Day of Resurrection), the Zalimun (polytheists and wrong-doers) fearful of that which they have earned, and it (Allah's Torment) will surely befall them. But those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous deeds (will be) in the flowering meadows of the Gardens (Paradise). They shall have whatsoever they desire with their Lord. That is the supreme Grace, (Paradise).

(152) That is (the Paradise) whereof Allah gives glad tidings to His slaves who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds. Say (O Muhammad صلى الله عليه و سلم): "No reward do I ask of you for this except to be kind to me for my kinship with you." And whoever earns a good righteous deed, We shall give him an increase of good in respect thereof. Verily, Allah is Oft-Forgiving, Most Ready to appreciate (the deeds of those who are obedient to Him).

(153) And He answers (the invocation of) those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds, and gives them increase of His Bounty. And as for the disbelievers, theirs will be a severe torment.

(154) Or do those who earn evil deeds think that We shall hold them equal with those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds, in their present life and after their death? Worst is the judgement that they make.

(155) Then, as for those who believed (in the Oneness of Allah - Islamic Monotheism) and did righteous good deeds, their Lord will admit them to His Mercy. That will be the evident success.

(156) And We have enjoined on man to be dutiful and kind to his parents. His mother bears him with hardship. And she brings him forth with hardship, and the bearing of him, and the weaning of him is thirty months, till when he attains full strength and reaches forty years, he says: "My Lord! Grant me the power and ability that I may be grateful for Your Favour which You have bestowed upon me and upon my parents, and that I may do righteous good deeds, such as please You, and make my offspring good. Truly, I have turned to You in repentance, and truly, I am one of the Muslims (submitting to Your Will)."

(157) But those who believe and do righteous good deeds, and believe in that which is sent down to Muhammad (صلى الله عليه وسلم) - for it is the truth from their Lord - He will expiate from them their sins, and will make good their state.

(158) Certainly Allah will admit those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds, to Gardens under which rivers flow (Paradise); while those who disbelieve enjoy themselves and eat as cattle eat; and the Fire will be their abode.

(159) Muhammad (صلى الله عليه وسلم) is the Messenger of Allah. And those who are with him are severe against disbelievers, and merciful among themselves. You see them bowing and falling down prostrate (in prayer), seeking Bounty from Allah and (His) Good Pleasure. The mark of them (i.e. of their Faith) is on their faces (foreheads) from the traces of prostration (during prayers). This is their description in the Taurat (Torah). But their description in the Injeel (Gospel) is like a (sown) seed which sends forth its shoot, then makes it strong, and becomes thick and it stands straight on its stem, delighting the sowers, that He may enrage the disbelievers with them. Allah has promised those among them who believe (i.e. all those who follow Islamic Monotheism, the religion of Prophet Muhammad صلى الله عليه وسلم till the Day of Resurrection) and do righteous good deeds, forgiveness and a mighty reward (i.e. Paradise).

(160) And those foremost [(in Islamic Faith of Monotheism and in performing righteous deeds) in the life of this world on the very first call for to embrace Islam] will be foremost (in Paradise).
