The word(s) "contend" appears 8 time(s) in 6 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) contend not on behalf of such as betray their own souls; for Allah loveth not one given to perfidy and crime:

(2) Ah! These are the sort of men on whose behalf ye may contend in this world; but who will contend with Allah on their behalf on the Day of Judgment, or who will carry their affairs through?

(3) If anyone contends with the Messenger even after guidance has been plainly conveyed to him, and follows a path other than that becoming to men of Faith, We shall leave him in the path he has chosen, and land him in Hell,- what an evil refuge!

(4) Eat not of (meats) on which Allah's name hath not been pronounced: That would be impiety. But the evil ones ever inspire their friends to contend with you if ye were to obey them, ye would indeed be Pagans.

(5) This because they contended against Allah and His Messenger: If any contend against Allah and His Messenger, Allah is strict in punishment.

(6) The Believers are but a single Brotherhood: So make peace and reconciliation between your two (contending) brothers; and fear Allah, that ye may receive Mercy.
