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

(31) Verily, that is the very truth - the mutual dispute of the people of the Fire!

(32) None disputes in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah but those who disbelieve. So let not their ability of going about here and there through the land (for their purposes) deceive you [O Muhammad صلى الله عليه وسلم, for their ultimate end will be the Fire of Hell]!

(33) The people of Nuh (Noah) and the Confederates after them denied (their Messengers) before these; and every (disbelieving) nation plotted against their Messenger to seize him, and disputed by means of falsehood to refute therewith the truth. So I seized them (with punishment), and how (terrible) was My punishment!

(34) Those who dispute about the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, without any authority that has come to them, it is greatly hateful and disgusting to Allah and to those who believe. Thus does Allah seal up the heart of every arrogant, tyrant. (So they cannot guide themselves to the Right Path).

(35) And, when they will dispute in the Fire, the weak will say to those who were arrogant: "Verily, we followed you: can you then take from us some portion of the Fire?"

(36) Verily those who dispute about the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, without any authority having come to them, there is nothing else in their breasts except pride [to accept you (Muhammad صلى الله عليه وسلم) as a Messenger of Allah and to obey you] . They will never have it (i.e. Prophethood which Allah has bestowed upon you). So seek refuge in Allah (O Muhammad صلى الله عليه وسلم from the arrogants). Verily, it is He Who is the All-Hearer, the All-Seer.

(37) See you not those who dispute about the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah? How are they turning away [from the truth, (i.e. Islamic Monotheism to the falsehood (i.e. polytheism)]?

(38) And indeed We gave Musa (Moses) the Scripture, but dispute arose therein. And had it not been for a Word that went forth before from your Lord, (the torment would have overtaken them) and the matter would have been settled between them. But truly, they are in grave doubt thereto (i.e. about the Qur'an). [Tafsir Al-Qurtubi].

(39) So unto this (religion of Islam alone and this Qur'an) then invite (people) (O Muhammad صلى الله عليه و سلم), and stand firm [on Islamic Monotheism by performing all that is ordained by Allah (good deeds), and by abstaining from all that is forbidden by Allah (sins and evil deeds)], as you are commanded, and follow not their desires but say: "I believe in whatsoever Allah has sent down of the Book [all the holy Books, - this Qur'an and the Books of the old from the Taurat (Torah), or the Injeel (Gospel) or the Pages of Ibrahim (Abraham)] and I am commanded to do justice among you. Allah is our Lord and your Lord. For us our deeds and for you your deeds. There is no dispute between us and you. Allah will assemble us (all), and to Him is the final return."

(40) And those who dispute concerning Allah (His religion of Islamic Monotheism with which Muhammad صلى الله عليه و سلم has been sent), after it has been accepted (by the people), of no use is their dispute before their Lord and on them is wrath, and for them will be a severe torment.
