The word(s) "dispute" appears 50 time(s) in 46 verse(s) in Quran in Mohsin Khan translation.

(21) And Ar-Ra'd (thunder) glorifies and praises Him, and so do the angels because of His Awe. He sends the thunderbolts, and therewith He strikes whom He wills, yet they (disbelievers) dispute about Allah. And He is Mighty in strength and Severe in punishment.

(22) Then, on the Day of Resurrection, He will disgrace them and will say: "Where are My (so called) partners concerning whom you used to disagree and dispute (with the believers, by defying and disobeying Allah)?" Those who have been given the knowledge (about the Torment of Allah for the disbelievers) will say: "Verily! Disgrace and misery this Day are upon the disbelievers.

(23) And thus We made their case known (to the people), that they might know that the Promise of Allah is true, and that there can be no doubt about the Hour. (Remember) when they (the people of the city) disputed among themselves about their case, they said: "Construct a building over them; their Lord knows best about them;" (then) those who won their point said (most probably the disbelievers): "We verily shall build a place of worship over them."

(24) And We send not the Messengers except as givers of glad tidings and warners. But those who disbelieve, dispute with false argument, in order to refute the truth thereby. And they treat My Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and that with which they are warned, as a jest and mockery!

(25) Such is 'Îsa (Jesus), son of Maryam (Mary). (It is) a statement of truth, about which they doubt (or dispute).

(26) And among mankind is he who disputes concerning Allah, without knowledge, and follows every rebellious (disobedient to Allah) Shaitan (devil) (devoid of every kind of good).

(27) And among men is he who disputes about Allah, without knowledge or guidance, or a Book giving light (from Allah),

(28) These two opponents (believers and disbelievers) dispute with each other about their Lord: then as for those who disbelieved, garments of fire will be cut out for them, boiling water will be poured down over their heads.

(29) For every nation We have ordained religious ceremonies [e.g. slaughtering of the cattle during the three days of stay at Mina (Makkah) during the Hajj (pilgrimage)] which they must follow; so let them (the pagans) not dispute with you on the matter (i.e. to eat of the cattle which you slaughter, and not to eat of the cattle which Allah kills by its natural death), but invite them to your Lord. Verily you (O Muhammad صلى الله عليه وسلم) indeed are on the (true) straight guidance (i.e. the true religion of Islamic Monotheism).

(30) See you not (O men) that Allah has subjected for you whatsoever is in the heavens and whatsoever is in the earth, and has completed and perfected His Graces upon you, (both) apparent (i.e. Islamic Monotheism, and the lawful pleasures of this world, including health, good looks, etc.) and hidden [i.e. One's Faith in Allah (of Islamic Monotheism) knowledge, wisdom, guidance for doing righteous deeds, and also the pleasures and delights of the Hereafter in Paradise]? Yet of mankind is he who disputes about Allah without knowledge or guidance or a Book giving light!
