The word(s) "straight" appears 56 time(s) in 56 verse(s) in Quran in Mohsin Khan translation.

(31) Say (O Muhammad صلى الله عليه وسلم): "Each one (believer and disbeliever.) is waiting, so wait you too; and you shall know who are they that are on the straight and Even Path (i.e. Allah's religion of Islamic Monotheism), and who are they that have let themselves be guided (on the Right Path).

(32) And that those who have been given knowledge may know that it (this Qur'an) is the truth from your Lord, so that they may believe therein, and their hearts may submit to it with humility. And verily, Allah is the Guide of those who believe, to the straight Path.

(33) For every nation We have ordained religious ceremonies [e.g. slaughtering of the cattle during the three days of stay at Mina (Makkah) during the Hajj (pilgrimage)] which they must follow; so let them (the pagans) not dispute with you on the matter (i.e. to eat of the cattle which you slaughter, and not to eat of the cattle which Allah kills by its natural death), but invite them to your Lord. Verily you (O Muhammad صلى الله عليه وسلم) indeed are on the (true) straight guidance (i.e. the true religion of Islamic Monotheism).

(34) And certainly, you (O Muhammad صلى الله عليه وسلم) call them to the straight Path (true religion - Islamic Monotheism).

(35) We have indeed sent down (in this Qur'an) manifest Ayat (proofs, evidence, verses, lessons, signs, revelations, lawful and unlawful things, and the set boundaries of Islamic religion, etc. that make things clear showing the Right Path of Allah). And Allah guides whom He wills to the straight Path (i.e. to Allah's religion of Islamic Monotheism).

(36) Those who will be gathered to Hell (prone) on their faces, such will be in an evil state, and most astray from the (straight) Path.

(37) "And weigh with the true and straight balance.

(38) So set you (O Muhammad صلى الله عليه وسلم) your face towards the religion (of pure Islamic Monotheism) Hanif (worship none but Allah Alone). Allah's Fitrah (i.e. Allah's Islamic Monotheism) with which He has created mankind. No change let there be in Khalq-illah (i.e. the religion of Allah - Islamic Monotheism): that is the straight religion, but most of men know not. [Tafsir At-Tabari]

(39) So set you (O Muhammad صلى الله عليه وسلم) your face (in obedience to Allah, your Lord) to the straight and right religion (Islamic Monotheism), before there comes from Allah a Day which none can avert. On that Day men shall be divided [(in two groups), a group in Paradise and a group in Hell].

(40) On the straight Path (i.e. on Allah's religion of Islamic Monotheism).
