The word(s) "mercy" appears 164 time(s) in 156 verse(s) in Quran in Abdullah Yusuf Ali translation.

(41) "And ordain for us that which is good, in this life and in the Hereafter: for we have turned unto Thee." He said: "With My punishment I visit whom I will; but My mercy extendeth to all things. That (mercy) I shall ordain for those who do right, and practise regular charity, and those who believe in Our signs;-

(42) If thou bring them not a revelation, they say: "Why hast thou not got it together?" Say: "I but follow what is revealed to me from my Lord: this is (nothing but) lights from your Lord, and Guidance, and mercy, for any who have faith."

(43) When the Qur'an is read, listen to it with attention, and hold your peace: that ye may receive mercy.

(44) And still the indignation of their hearts. For Allah will turn (in mercy) to whom He will; and Allah is All-Knowing, All-Wise.

(45) Their Lord doth give them glad tidings of a mercy from Himself, of His good pleasure, and of gardens for them, wherein are delights that endure:

(46) Again will Allah, after this, turn (in mercy) to whom He will: for Allah is Oft-forgiving, Most Merciful.

(47) Among them are men who molest the Prophet and say, "He is (all) ear." Say, "He listens to what is best for you: he believes in Allah, has faith in the Believers, and is a mercy to those of you who believe." But those who molest the Messenger will have a grievous penalty.

(48) The Believers, men and women, are protectors one of another: they enjoin what is just, and forbid what is evil: they observe regular prayers, practise regular charity, and obey Allah and His Messenger. On them will Allah pour His mercy: for Allah is Exalted in power, Wise.

(49) But some of the desert Arabs believe in Allah and the Last Day, and look on their payments as pious gifts bringing them nearer to Allah and obtaining the prayers of the Messenger. Aye, indeed they bring them nearer (to Him): soon will Allah admit them to His mercy: for Allah is Oft-forgiving, Most Merciful.

(50) Others (there are who) have acknowledged their wrong-doings: they have mixed an act that was good with another that was evil. Perhaps Allah will turn unto them (in mercy): for Allah is Oft-Forgiving, Most Merciful.
