The word(s) "merciful" appears 147 time(s) in 130 verse(s) in Quran in Muhammad Habib Shakir translation.

(21) Repentance with Allah is only for those who do evil in ignorance, then turn (to Allah) soon, so these it is to whom Allah turns (mercifully), and Allah is ever Knowing, Wise.

(22) Forbidden to you are your mothers and your daughters and your sisters and your paternal aunts and your maternal aunts and brothers' daughters and sisters' daughters and your mothers that have suckled you and your foster-sisters and mothers of your wives and your step-daughters who are in your guardianship, (born) of your wives to whom you have gone in, but if you have not gone in to them, there is no blame on you (in marrying them), and the wives of your sons who are of your own loins and that you should have two sisters together, except what has already passed; surely Allah is Forgiving, merciful.

(23) And whoever among you has not within his power ampleness of means to marry free believing women, then (he may marry) of those whom your right hands possess from among your believing maidens; and Allah knows best your faith: you are (sprung) the one from the other; so marry them with the permission of their masters, and give them their dowries justly, they being chaste, not fornicating, nor receiving paramours; and when they are taken in marriage, then if they are guilty of indecency, they shall suffer half the punishment which is (inflicted) upon free women. This is for him among you who fears falling into evil; and that you abstain is better for you, and Allah is Forgiving, merciful.

(24) Allah desires to explain to you, and to guide you into the ways of those before you, and to turn to you (mercifully), and Allah is Knowing, Wise.

(25) And Allah desires that He should turn to you (mercifully), and those who follow (their) lusts desire that you should deviate (with) a great deviation.

(26) O you who believe! do not devour your property among yourselves falsely, except that it be trading by your mutual consent; and do not kill your people; surely Allah is merciful to you.

(27) And We did not send any apostle but that he should be obeyed by Allah's permission; and had they, when they were unjust to themselves, come to you and asked forgiveness of Allah and the Apostle had (also) asked forgiveness for them, they would have found Allah Oft-returning (to mercy), merciful.

(28) (High) degrees from Him and protection and mercy, and Allah is Forgiving, merciful.

(29) And whoever flies in Allah's way, he will find in the earth many a place of refuge and abundant resources, and whoever goes forth from his house flying to Allah and His Apostle, and then death overtakes him, his reward is indeed with Allah and Allah is Forgiving, merciful.

(30) And ask forgiveness of Allah; surely Allah is Forgiving, merciful.
