The word(s) "mercy" appears 168 time(s) in 158 verse(s) in Quran in Mohsin Khan translation.

(1) Then after that you turned away. Had it not been for the Grace and mercy of Allah upon you, indeed you would have been among the losers.

(2) Neither those who disbelieve among the people of the Scripture (Jews and Christians) nor Al-Mushrikun (the idolaters, polytheists, disbelievers in the Oneness of Allah, pagans, etc.) like that there should be sent down unto you any good from your Lord. But Allah chooses for His mercy whom He wills. And Allah is the Owner of Great Bounty.

(3) They are those on whom are the Salawat (i.e. who are blessed and will be forgiven) from their Lord, and (they are those who) receive His mercy, and it is they who are the guided ones.

(4) O you who believe! Al-Qisas (the Law of Equality in punishment) is prescribed for you in case of murder: the free for the free, the slave for the slave, and the female for the female. But if the killer is forgiven by the brother (or the relatives, etc.) of the killed against blood-money, then adhering to it with fairness and payment of the blood-money to the heir should be made in fairness. This is an alleviation and a mercy from your Lord. So after this whoever transgresses the limits (i.e. kills the killer after taking the blood-money), he shall have a painful torment.

(5) Verily, those who have believed, and those who have emigrated (for Allah's Religion) and have striven hard in the Way of Allah, all these hope for Allah's mercy. And Allah is Oft-Forgiving, Most-Merciful.

(6) Allah burdens not a person beyond his scope. He gets reward for that (good) which he has earned, and he is punished for that (evil) which he has earned. "Our Lord! Punish us not if we forget or fall into error, our Lord! Lay not on us a burden like that which You did lay on those before us (Jews and Christians); our Lord! Put not on us a burden greater than we have strength to bear. Pardon us and grant us Forgiveness. Have mercy on us. You are our Maula (Patron, Supporter and Protector, etc.) and give us victory over the disbelieving people. "

(7) (They say): "Our Lord! Let not our hearts deviate (from the truth) after You have guided us, and grant us mercy from You. Truly, You are the Bestower."

(8) He selects for His mercy (Islam and the Qur'an with Prophethood) whom He wills and Allah is the Owner of Great Bounty.

(9) And for those whose faces will become white, they will be in Allah's mercy (Paradise), therein they shall dwell forever.

(10) Not for you (O Muhammad صلى الله عليه وسلم, but for Allah) is the decision; whether He turns in mercy to (pardons) them or punishes them; verily, they are the Zalimun (polytheists, disobedients, and wrong-doers).
