The word(s) "truth" appears 333 time(s) in 316 verse(s) in Quran in Abdullah Yusuf Ali translation.

(31) They (also) said: "Allah took our promise not to believe in an messenger unless He showed us a sacrifice consumed by Fire (From heaven)." Say: "There came to you messengers before me, with clear Signs and even with what ye ask for: why then did ye slay them, if ye speak the truth?"

(32) All who obey Allah and the messenger are in the company of those on whom is the Grace of Allah,- of the prophets (who teach), the sincere (lovers of truth), the witnesses (who testify), and the Righteous (who do good): Ah! what a beautiful fellowship!

(33) We have sent down to thee the Book in truth, that thou mightest judge between men, as guided by Allah: so be not (used) as an advocate by those who betray their trust;

(34) But those who believe and do deeds of righteousness,- we shall soon admit them to gardens, with rivers flowing beneath,-to dwell therein for ever. Allah's promise is the truth, and whose word can be truer than Allah's?

(35) They are in truth (equally) unbelievers; and we have prepared for unbelievers a humiliating punishment.

(36) O Mankind! The Messenger hath come to you in truth from Allah: believe in him: It is best for you. But if ye reject Faith, to Allah belong all things in the heavens and on earth: And Allah is All-knowing, All-wise.

(37) O People of the Book! Commit no excesses in your religion: Nor say of Allah aught but the truth. Christ Jesus the son of Mary was (no more than) a messenger of Allah, and His Word, which He bestowed on Mary, and a spirit proceeding from Him: so believe in Allah and His messengers. Say not "Trinity": desist: it will be better for you: for Allah is one Allah: Glory be to Him: (far exalted is He) above having a son. To Him belong all things in the heavens and on earth. And enough is Allah as a Disposer of affairs.

(38) Recite to them the truth of the story of the two sons of Adam. Behold! they each presented a sacrifice (to Allah): It was accepted from one, but not from the other. Said the latter: "Be sure I will slay thee." "Surely," said the former, "Allah doth accept of the sacrifice of those who are righteous.

(39) To thee We sent the Scripture in truth, confirming the scripture that came before it, and guarding it in safety: so judge between them by what Allah hath revealed, and follow not their vain desires, diverging from the truth that hath come to thee. To each among you have we prescribed a law and an open way. If Allah had so willed, He would have made you a single people, but (His plan is) to test you in what He hath given you: so strive as in a race in all virtues. The goal of you all is to Allah; it is He that will show you the truth of the matters in which ye dispute;

(40) Christ the son of Mary was no more than a messenger; many were the messengers that passed away before him. His mother was a woman of truth. They had both to eat their (daily) food. See how Allah doth make His signs clear to them; yet see in what ways they are deluded away from the truth!
