The word(s) "true" appears 123 time(s) in 116 verse(s) in Quran in Mohsin Khan translation.

(51) Verily, in this (the Qur'an) there is a plain Message for people who worship Allah (i.e. the true, real believers of Islamic Monotheism who act practically on the Qur'an and the Sunnah - legal ways of the Prophet صلى الله عليه وسلم).

(52) And for every nation We have appointed religious ceremonies, that they may mention the Name of Allah over the beast of cattle that He has given them for food. And your Ilah (God) is One Ilah (God - Allah), so you must submit to Him Alone (in Islam). And (O Muhammad صلى الله عليه وسلم) give glad tidings to the Mukhbitun (those who obey Allah with humility and are humble from among the true believers of Islamic Monotheism),

(53) That is because Allah - He is the Truth (the only true God of all that exists, Who has no partners or rivals with Him), and what they (the polytheists) invoke besides Him, it is Batil (falsehood). And verily, Allah - He is the Most High, the Most Great.

(54) 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).

(55) Those who are faithfully true to their Amanat (all the duties which Allah has ordained, honesty, moral responsibility and trusts) and to their covenants;

(56) Then We sent Our Messengers in succession. Every time there came to a nation their Messenger, they denied him; so We made them follow one another (to destruction), and We made them as Ahadith (the true stories for mankind to learn a lesson from them). So away with a people who believe not!

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

(58) And verily, those who believe not in the Hereafter are indeed deviating far astray from the Path (true religion - Islamic Monotheism).

(59) So Exalted be Allah, the true King: La ilaha illa Huwa (none has the right to be worshipped but He), the Lord of the Supreme Throne!

(60) The true believers are only those, who believe in (the Oneness of) Allah and His Messenger (Muhammad صلى الله عليه وسلم): and when they are with him on some common matter, they go not away until they have asked his permission. Verily those who ask your permission, those are they who (really) believe in Allah and His Messenger. So if they ask your permission for some affairs of theirs, give permission to whom you will of them, and ask Allah for their forgiveness. Truly, Allah is Oft-Forgiving, Most Merciful.
