The word(s) "differ" appears 53 time(s) in 45 verse(s) in Quran in Mohsin Khan translation.

(31) Verily, your Lord will judge between them, on the Day of Resurrection, concerning that wherein they used to differ.

(32) Surely the religion (i.e. the worship and the obedience) is for Allah only. And those who take Auliya' (protectors, helpers, lords, gods) besides Him (say): "We worship them only that they may bring us near to Allah." Verily Allah will judge between them concerning that wherein they differ. Truly, Allah guides not him who is a liar, and a disbeliever.

(33) See you not that Allah sends down water (rain) from the sky, and causes it to penetrate the earth, (and then makes it to spring up) as water-springs, and afterward thereby produces crops of different colours, and afterward they wither and you see them turn yellow; then He makes them dry and broken pieces. Verily, in this is a Reminder for men of understanding.

(34) Say (O Muhammad صلى الله عليه وسلم): "O Allah! Creator of the heavens and the earth! All-Knower of the Ghaib (Unseen) and the seen! You will judge between your slaves about that wherein they used to differ."

(35) And in whatsoever you differ, the decision thereof is with Allah (He is the ruling Judge). (And say O Muhammad صلى الله عليه و سلم to these polytheists:) Such is Allah, my Lord in Whom I put my trust, and to Him I turn (in all of my affairs and) in repentance.

(36) And when 'Îsa (Jesus) came with (Our) clear Proofs, he said: "I have come to you with Al-Hikmah (Prophethood), and in order to make clear to you some of the (points) in which you differ. Therefore fear Allah and obey me.

(37) But the sects from among themselves differed. So woe to those who do wrong [by ascribing things to 'Îsa (Jesus) that are not true] from the torment of a painful Day (i.e. the Day of Resurrection)!

(38) And gave them clear proofs in matters [by revealing to them the Taurat (Torah)]. And they differed not until after the knowledge came to them, through envy among themselves. Verily, Your Lord will judge between them on the Day of Resurrection about that wherein they used to differ.

(39) Nay, but they have denied the truth (this Qur'an) when it has come to them, so they are in a confused state (cannot differentiate between right and wrong).

(40) Certainly, you have different ideas (about Muhammad صلى الله عليه وسلم and the Qur'an).
