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

(31) With regard to a believer, they respect not the ties, either of kinship or of covenant! It is they who are the transgressors.

(32) But if they violate their oaths after their covenant, and attack your religion with disapproval and criticism, then fight (you) the leaders of disbelief (chiefs of Quraish pagans of Makkah) - for surely their oaths are nothing to them - so that they may stop (evil actions).

(33) And of them are some who made a covenant with Allah (saying): "If He bestowed on us of His Bounty, we will verily give Sadaqah (Zakat and voluntary charity in Allah's Cause) and will be certainly among those who are righteous."

(34) So He punished them by putting hypocrisy into their hearts till the Day whereon they shall meet Him, because they broke that (covenant with Allah) which they had promised to Him and because they used to tell lies.

(35) Verily, Allah has purchased of the believers their lives and their properties for (the price) that theirs shall be the Paradise. They fight in Allah's Cause, so they kill (others) and are killed. It is a promise in truth which is binding on Him in the Taurat (Torah) and the Injeel (Gospel) and the Qur'an. And who is truer to his covenant than Allah? Then rejoice in the bargain which you have concluded. That is the supreme success.

(36) Those who fulfil the covenant of Allah and break not the Mithaq (bond, treaty, covenant).

(37) And those who break the covenant of Allah, after its ratification, and sever that which Allah has commanded to be joined (i.e. they sever the bond of kinship and are not good to their relatives), and work mischief in the land, on them is the curse (i.e. they will be far away from Allah's Mercy), and for them is the unhappy (evil) home (i.e. Hell) .

(38) And fulfil the covenant of Allah (Bai'ah: pledge for Islam) when you have covenanted, and break not the oaths after you have confirmed them - and indeed you have appointed Allah your surety. Verily! Allah knows what you do.

(39) And be not like her who undoes the thread which she has spun, after it has become strong, by taking your oaths as a means of deception among yourselves, lest a nation should be more numerous than another nation. Allah only tests you by this [i.e who obeys Allah and fulfils Allah's covenant and who disobeys Allah and breaks Allah's covenant]. And on the Day of Resurrection, He will certainly make clear to you that wherein you used to differ [i.e. a believer confesses and believes in the Oneness of Allah and in the Prophethood of Prophet Muhammad صلى الله عليه و سلم which the disbeliever denies and that is their difference amongst them in the life of this world] .

(40) And purchase not a small gain at the cost of Allah's covenant. Verily! What is with Allah is better for you if you did but know.
