The word(s) "claim" appears 24 time(s) in 22 verse(s) in Quran in Mohsin Khan translation.

(11) And (remember) when your Lord proclaimed: "If you give thanks (by accepting Faith and worshipping none but Allah), I will give you more (of My Blessings); but if you are thankless (i.e. disbelievers), verily My punishment is indeed severe."

(12) Therefore proclaim openly (Allah's Message - Islamic Monotheism) that which you are commanded, and turn away from Al-Mushrikun (polytheists, idolaters, and disbelievers - See V.2:105).

(13) 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).

(14) And proclaim to mankind the Hajj (pilgrimage). They will come to you on foot and on every lean camel, they will come from every deep and distant (wide) mountain highway (to perform Hajj ).

(15) And when they shall be thrown into a narrow place thereof, chained together, they will exclaim therein for destruction.

(16) Exclaim not today for one destruction, but exclaim for many destructions.

(17) And Fir'aun (Pharaoh) proclaimed among his people (saying): "O my people! Is not mine the dominion of Egypt, and these rivers flowing underneath me. See you not then?

(18) Say (O Muhammad صلى الله عليه و سلم): "If the Most Gracious (Allah) had a son (or children as you pretend), then I am the first of Allah's worshippers [who deny and refute this claim of yours (and the first to believe in Allah Alone and testify that He has no children)]." [Tafsir At-Tabari].

(19) Say (O Muhammad صلى الله عليه وسلم to these pagans): "Think you about all that you invoke besides Allah? Show me. What have they created of the earth? Or have they a share in (the creation of) the heavens? Bring me a Book (revealed before this), or some trace of knowledge (in support of your claims), if you are truthful!"

(20) O you who believe (Muslims)! When the call is proclaimed for the Salat (prayer) on Friday (Jumu'ah prayer), come to the remembrance of Allah [Jumu'ah religious talk (Khutbah) and Salat (prayer)] and leave off business (and every other thing). That is better for you if you did but know!
