The word(s) "covenant" appears 70 time(s) in 55 verse(s) in Quran in Mohsin Khan translation.

(51) But when We removed the torment from them, behold, they broke their covenant (that they will believe if We remove the torment from them).

(52) Verily, those who give Bai'ah (pledge) to you (O Muhammad صلى الله عليه وسلم) they are giving Bai'ah (pledge) to Allah. The Hand of Allah is over their hands. Then whosoever breaks his pledge, breaks it only to his own harm; and whosoever fulfils what he has covenanted with Allah, He will bestow on him a great reward.

(53) (It will be said): "This is what you were promised - (it is) for those oft-returning (to Allah) in sincere repentance, and those who preserve their covenant with Allah (by obeying Him in all what He has ordered, and worshipping none but Allah Alone, i.e. follow Allah's religion - Islamic Monotheism).

(54) And what is the matter with you that you believe not in Allah! While the Messenger (Muhammad صلى الله عليه وسلم) invites you to believe in your Lord (Allah); and He (Allah) has indeed taken your covenant, if you are real believers.

(55) And those who keep their trusts and covenants.
