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

(151) Those who believed (in the Oneness of Allah - Islamic Monotheism), and work righteousness, Tuba (all kinds of happiness or name of a tree in Paradise) is for them and a beautiful place of (final) return.

(152) Thus have We sent you (O Muhammad صلى الله عليه و سلم) to a community before whom other communities have passed away, in order that you might recite unto them what We have revealed to you, while they disbelieve in the Most Gracious (Allah) Say: "He is my Lord! La ilaha illa Huwa (none has the right to be worshipped but He)! In Him is my trust, and to Him will be my return with repentance."

(153) Is then He (Allah) Who takes charge (guards, maintains, provides) of every person and knows all that he has earned (like any other deities who know nothing)? Yet, they ascribe partners to Allah. Say: "Name them! Is it that you will inform Him of something He knows not in the earth or is it (just) a show of false words." Nay! To those who disbelieved, their plotting is made fairseeming, and they have been hindered from the right Path; and whom Allah sends astray, for him there is no guide.

(154) The parable of those who disbelieved in their Lord is that their works are as ashes, on which the wind blows furiously on a stormy day; they shall not be able to get aught of what they have earned. That is the straying, far away (from the right Path).

(155) And those who believed (in the Oneness of Allah and His Messengers and whatever they brought) and did righteous deeds, will be made to enter Gardens under which rivers flow, - to dwell therein for ever (i.e. in Paradise), with the Permission of their Lord. Their greeting therein will be: Salam (peace!).

(156) This (Qur'an) is a Message for mankind (and a clear proof against them), in order that they may be warned thereby, and that they may know that He is the only One Ilah (God - Allah) - (none has the right to be worshipped but Allah) - and that men of understanding may take heed.

(157) And verily! They (the cities) were right on the highroad (from Makkah to Syria i.e. the place where the Dead Sea is now) .

(158) He sends down the angels with the Ruh (revelation) of His Command to whom of His slaves He wills (saying): "Warn mankind that La ilaha illa Ana (none has the right to be worshipped but I), so fear Me (by abstaining from sins and evil deeds).

(159) Your Ilah (God) is One Ilah (God - Allah, none has the right to be worshipped but He). But for those who believe not in the Hereafter, their hearts deny (the faith in the Oneness of Allah), and they are proud.

(160) Have they not observed things that Allah has created: (how) their shadows incline to the right and to the left, making prostration unto Allah, and they are lowly?
