The word(s) "right" appears 460 time(s) in 433 verse(s) in Quran in Mohsin Khan translation.

(171) And whoever desires the Hereafter and strives for it, with the necessary effort due for it (i.e. does righteous deeds of Allah's Obedience) while he is a believer (in the Oneness of Allah - Islamic Monotheism) - then such are the ones whose striving shall be appreciated, (thanked and rewarded by Allah).

(172) Your Lord knows best what is in your inner-selves. If you are righteous, then, verily, He is Ever Most Forgiving to those who turn unto Him again and again in obedience, and in repentance.

(173) And if you (O Muhammad صلى الله عليه و سلم) turn away from them (kindred, poor, wayfarer whom We have ordered you to give their rights, but if you have no money at the time they ask you for it) and you are awaiting a mercy from your Lord for which you hope, then, speak unto them a soft kind word (i.e. Allah will give me and I shall give you).

(174) And We have put coverings over their hearts lest they should understand it (the Qur'an), and in their ears deafness. And when you make mention of your Lord Alone [La ilaha illallah (none has the right to be worshipped but Allah) Islamic Monotheism (توحيد الله)] in the Qur'an, they turn on their backs, fleeing in extreme dislike.

(175) (And remember) the Day when We shall call together call human beings with their (respective) Imam [their Prophets, or their records of good and bad deeds, or their Holy Books like the Qur'an, the Taurat (Torah), the Injeel (Gospel), the leaders whom the people followed in this world.]. So whosoever is given his record in his right hand, such will read their records, and they will not be dealt with unjustly in the least.

(176) And verily they were about to frighten you so much as to drive you out from the land. But in that case they would not have stayed (therein) after you, except for a little while.

(177) And when We bestow Our Grace on man (the disbeliever), he turns away and becomes arrogant (far away from the right Path). And when evil touches him, he is in great despair.

(178) Say (O Muhammad صلى الله عليه و سلم to mankind): "Each one does according to Shakilatihi (i.e. his way or his religion or his intentions.), and your Lord knows best of him whose path (religion) is right."

(179) And he whom Allah guides, he is led aright; but he whom He sends astray, for such you will find no Auliya' (helpers and protectors), besides Him, and We shall gather them together on the Day of Resurrection on their faces, blind, dumb and deaf; their abode will be Hell; whenever it abates, We shall increase for them the fierceness of the Fire.

(180) (He has made it) straight to give warning (to the disbelievers) of a severe punishment from Him, and to give glad tidings to the believers (in the Oneness of Allah - Islamic Monotheism), who do righteous deeds, that they shall have a fair reward (i.e. Paradise).
