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

(131) "Why do you not bring angels to us if you are of the truthful?"

(132) We send not the angels down except with the truth (i.e. for torment), and in that case, they (the disbelievers) would have no respite!

(133) They (the angels) said: "We give you glad tidings in truth. So be not of the despairing."

(134) "And we have brought you the truth (the news of the destruction of your nation) and certainly, we tell the truth.

(135) And We created not the heavens and the earth and all that is between them except with truth, and the Hour is surely coming, so overlook (O Muhammad صلى الله عليه و سلم) their faults with gracious forgiveness. [This was before the ordainment of Jihad - holy fighting in Allah's cause].

(136) He has created the heavens and the earth with truth. High is He, Exalted above all that they associate as partners with Him.

(137) And verily, We have sent among every Ummah (community, nation) a Messenger (proclaiming): "Worship Allah (Alone), and avoid (or keep away from) Taghut (all false deities i.e. do not worship Taghut besides Allah)." Then of them were some whom Allah guided and of them were some upon whom the straying was justified. So travel through the land and see what was the end of those who denied (the truth).

(138) And they swear by Allah their strongest oaths, that Allah will not raise up him who dies. Yes, (He will raise them up), - a promise (binding) upon Him in truth, but most of mankind know not.

(139) In order that He may make manifest to them the truth of that wherein they differ, and that those who disbelieved (in Resurrection, and in the Oneness of Allah) may know that they were liars.

(140) Say (O Muhammad صلى الله عليه و سلم) Ruh-ul-Qudus [Jibril (Gabriel)] has brought it (the Qur'an) down from your Lord with truth, that it may make firm and strengthen (the Faith of) those who believe, and as a guidance and glad tidings to those who have submitted (to Allah as Muslims).
