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

(31) So if they dispute with you (Muhammad صلى الله عليه وسلم) say: "I have submitted myself to Allah (in Islam), and (so have) those who follow me." And say to those who were given the Scripture (Jews and Christians) and to those who are illiterates (Arab pagans): "Do you (also) submit yourselves (to Allah in Islam)?" If they do, they are rightly guided; but if they turn away, your duty is only to convey the Message; and Allah is All-Seer of (His) slaves .

(32) Verily! Those who disbelieve in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah and kill the Prophets without right, and kill those men who order just dealings, ... then announce to them a painful torment.

(33) 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."

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

(35) Our Lord! We believe in what You have sent down, and we follow the Messenger [('Îsa (Jesus)]; so write us down among those who bear witness (to the truth i.e. La ilaha illallah - none has the right to be worshipped but Allah).

(36) 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).

(37) Verily! This is the true narrative [about the story of 'Îsa (Jesus)], and La ilaha illallah (none has the right to be worshipped but Allah, the One and the Only True God, Who has neither a wife nor a son). And indeed, Allah is the All-Mighty, the All-Wise.

(38) And believe no one except the one who follows your religion. Say (O Muhammad صلى الله عليه وسلم): "Verily! right guidance is the Guidance of Allah" and do not believe that anyone can receive like that which you have received, otherwise they would engage you in argument before your Lord. Say (O Muhammad صلى الله عليه وسلم): "All the bounty is in the Hand of Allah; He grants to whom He wills. And Allah is All-Sufficient for His creatures' needs, All-Knower."

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

(40) 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.
