The word(s) "mercy" appears 151 time(s) in 147 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Then Adam received (some) words from his Lord, so He turned to him mercifully; surely He is Oft-returning (to mercy), the Merciful.

(2) And when Musa said to his people: O my people! you have surely been unjust to yourselves by taking the calf (for a god), therefore turn to your Creator (penitently), so kill your people, that is best for you with your Creator: so He turned to you (mercifully), for surely He is the Oft-returning (to mercy), the Merciful.

(3) Then you turned back after that; so were it not for the grace of Allah and His mercy on you, you would certainly have been among the losers.

(4) Those who disbelieve from among the followers of the Book do not like, nor do the polytheists, that the good should be sent down to you from your Lord, and Allah chooses especially whom He pleases for His mercy, and Allah is the Lord of mighty grace.

(5) Our Lord! and make us both submissive to Thee and (raise) from our offspring a nation submitting to Thee, and show us our ways of devotion and turn to us (mercifully), surely Thou art the Oft-returning (to mercy), the Merciful.

(6) Those are they on whom are blessings and mercy from their Lord, and those are the followers of the right course.

(7) Except those who repent and amend and make manifest (the truth), these it is to whom I turn (mercifully); and I am the Oft-returning (to mercy), the Merciful.

(8) O you who believe! retaliation is prescribed for you in the matter of the slain, the free for the free, and the slave for the slave, and the female for the female, but if any remission is made to any one by his (aggrieved) brother, then prosecution (for the bloodwit) should be made according to usage, and payment should be made to him in a good manner; this is an alleviation from your Lord and a mercy; so whoever exceeds the limit after this he shall have a painful chastisement.

(9) Surely those who believed and those who fled (their home) and strove hard in the way of Allah these hope for the mercy of Allah and Allah is Forgiving, Merciful.

(10) Allah does not impose upon any soul a duty but to the extent of its ability; for it is (the benefit of) what it has earned and upon it (the evil of) what it has wrought: Our Lord! do not punish us if we forget or make a mistake; Our Lord! do not lay on us a burden as Thou didst lay on those before us, Our Lord do not impose upon us that which we have not the strength to bear; and pardon us and grant us protection and have mercy on us, Thou art our Patron, so help us against the unbelieving people.
