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

(131) And He it is Who sends down the rain after they have despaired, and He unfolds His mercy; and He is the Guardian, the Praised One.

(132) But if they turn aside, We have not sent you as a watcher over them; on you is only to deliver (the message); and surely when We make man taste mercy from Us, he rejoices thereat; and if an evil afflicts them on account of what their hands have already done, then-surely man is ungrateful.

(133) Will they distribute the mercy of your Lord? We distribute among them their livelihood in the life of this world, and We j have exalted some of them above others in degrees, that some of them may take others in subjection; and the mercy of your Lord is better than what they amass.

(134) A mercy from your Lord, surely He is the Hearing, the Knowing,

(135) Save those on whom Allah shall have mercy; surely He is the Mighty the Merciful.

(136) These are clear proofs for men, and a guidance and a mercy for a people who are sure.

(137) Then as to those who believed and did good, their Lord will make them enter into His mercy; that is the manifest achievement.

(138) And before it the Book of Musa was a guide and a mercy: and this is a Book verifying (it) in the Arabic language that it may warn those who are unjust and as good news for the doers of good.

(139) It is they who disbelieved and turned you away from the Sacred Mosque and (turned off) the offering withheld from arriving at its destined place; and were it not for the believing men and the believing women, whom, not having known, you might have trodden down, and thus something hateful might have afflicted you on their account without knowledge-- so that Allah may cause to enter into His mercy whomsoever He pleases; had they been widely separated one from another, We would surely have punished those who disbelieved from among them with a painful punishment.

(140) The believers are but brethren, therefore make peace between your brethren and be careful of (your duty to) Allah that mercy may be had on you.
