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

(151) And mention in the Book (the Qur'an) Idris (Enoch).Verily he was a man of truth, (and) a Prophet.

(152) "Truly, it has been revealed to us that the torment will be for him who denies [believes not in the Oneness of Allah, and in His Messengers.], and turns away (from the truth and obedience of Allah)."

(153) Nay, We fling (send down) the truth (this Qur'an) against the falsehood (disbelief), so it destroys it, and behold, it (falsehood) is vanished. And woe to you for that (lie) which you ascribe (to Allah by uttering that Allah has a wife and a son).

(154) Or have they taken for worship (other) alihah (gods) besides Him? Say: "Bring your proof." This (the Qur'an) is the Reminder for those with me and the Reminder for those before me. But most of them know not the truth, so they are averse.

(155) And they say: "When will this promise (come to pass), if you are truthful."

(156) They said: "Have you brought us the truth, or are you one of those who play about?"

(157) He (Muhammad صلى الله عليه وسلم) said: "My Lord! Judge You in truth! Our Lord is the Most Gracious, Whose Help is to be sought against that which you attribute (unto Allah that He has offspring, and unto Muhammad صلى الله عليه وسلم that he is a sorcerer, and unto the Qur'an that it is poetry)!"

(158) That is because Allah: He is the truth, and it is He Who gives life to the dead, and it is He Who is Able to do all things.

(159) That He (Allah) may make what is thrown in by Shaitan (Satan) a trial for those in whose hearts is a disease (of hypocrisy and disbelief) and whose hearts are hardened. And certainly, the Zalimun (polytheists and wrong-doers) are in an opposition far-off (from the truth against Allah's Messenger and the believers).

(160) 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.
