The word(s) "truth" appears 330 time(s) in 304 verse(s) in Quran in Mohsin Khan translation.

(31) Say (O Muhammad صلى الله عليه وسلم): "Allah has spoken the truth; follow the religion of Ibrahim (Abraham) Hanifa (Islamic Monotheism, i.e. he used to worship Allah Alone), and he was not of Al-Mushrikun " (See V.2:105)

(32) These are the Verses of Allah: We recite them to you (O Muhammad صلى الله عليه وسلم) in truth, and Allah wills no injustice to the 'Alamin (mankind, jinn and all that exists).

(33) (They are) the ones who said about their killed brethren while they themselves sat (at home): "If only they had listened to us, they would not have been killed." Say: "Avert death from your ownselves, if you speak the truth."

(34) Those (Jews) who said: "Verily, Allah has taken our promise not to believe in any Messenger unless he brings to us an offering which the fire (from heaven) shall devour." Say: "Verily, there came to you Messengers before me, with clear signs and even with what you speak of; why then did you kill them, if you are truthful?"

(35) O you who believe! When you go (to fight) in the Cause of Allah, verify (the truth), and say not to anyone who greets you (by embracing Islam): "You are not a believer"; seeking the perishable goods of the worldly life. There are much more profits and booties with Allah. Even as he is now, so were you yourselves before till Allah conferred on you His Favours (i.e. guided you to Islam), therefore, be cautious in discrimination. Allah is Ever Well-Aware of what you do.

(36) Surely, We have sent down to you (O Muhammad صلى الله عليه وسلم) the Book (this Qur'an) in truth that you might judge between men by that which Allah has shown you (i.e. has taught you through Divine Revelation), so be not a pleader for the treacherous.

(37) But those who believe (in the Oneness of Allah - Islamic Monotheism) and do deeds of righteousness, We shall admit them to the Gardens under which rivers flow (i.e. in Paradise) to dwell therein forever. Allah's Promise is the truth; and whose words can be truer than those of Allah? (Of course, none).

(38) (They are) swaying between this and that, belonging neither to these nor to those; and he whom Allah sends astray, you will not find for him a way (to the truth - Islam).

(39) They are in truth disbelievers. And We have prepared for the disbelievers a humiliating torment.

(40) Verily, those who disbelieve [by concealing the truth about Prophet Muhammad صلى الله عليه وسلم and his message of true Islamic Monotheism written in the Taurat (Torah) and the Injeel (Gospel) with them] and prevent (mankind) from the Path of Allah (Islamic Monotheism); they have certainly strayed far away.
