The word(s) "truth" appears 293 time(s) in 276 verse(s) in Quran in Muhammad Pickthal translation.

(161) I found her and her people worshipping the sun instead of Allah; and Satan maketh their works fairseeming unto them, and debarreth them from the way (of truth), so that they go not aright;

(162) (Solomon) said: We shall see whether thou speakest truth or whether thou art of the liars.

(163) They said: Swear one to another by Allah that we verily will attack him and his household by night, and afterward we will surely say unto his friend: We witnessed not the destruction of his household. And lo! we are truthtellers.

(164) Is not He (best) Who produceth creation, then reproduceth it, and Who provideth for you from the heaven and the earth? Is there any Allah beside Allah? Say: Bring your proof, if ye are truthful!

(165) And they say: When (will) this promise (be fulfilled), if ye are truthful?

(166) Therefor (O Muhammad) put thy trust in Allah, for thou (standest) on the plain truth.

(167) We narrate unto thee (somewhat) of the story of Moses and Pharaoh with truth, for folk who believe.

(168) But when there came unto them the truth from Our presence, they said: Why is he not given the like of what was given unto Moses? Did they not disbelieve in that which was given unto Moses of old? They say: Two magics that support each other; and they say: Lo! in both we are disbelievers.

(169) Say (unto them, O Muhammad): Then bring a scripture from the presence of Allah that giveth clearer guidance than these two (that) I may follow it, if ye are truthful.

(170) And when it is recited unto them, they say: We believe in it. Lo! it is the truth from our Lord. Lo! even before it we were of those who surrender (unto Him).
