The word(s) "differ" appears 39 time(s) in 33 verse(s) in Quran in Muhammad Pickthal translation.

(31) And the difference of night and day and the provision that Allah sendeth down from the sky and thereby quickeneth the earth after her death, and the ordering of the winds, are portents for a people who have sense.

(32) And gave them plain commandments. And they differed not until after the knowledge came unto them, through rivalry among themselves. Lo! thy Lord will judge between them on the Day of Resurrection concerning that wherein they used to differ.

(33) And among us there are righteous folk and among us there are far from that. We are sects having different rules.
