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

(131) Or have they the treasures of the mercy of thy Lord,- the Exalted in Power, the Grantor of Bounties without measure?

(132) Is one who worships devoutly during the hour of the night prostrating himself or standing (in adoration), who takes heed of the Hereafter, and who places his hope in the mercy of his Lord - (like one who does not)? Say: "Are those equal, those who know and those who do not know? It is those who are endued with understanding that receive admonition.

(133) Say: "O my Servants who have transgressed against their souls! Despair not of the mercy of Allah: for Allah forgives all sins: for He is Oft-Forgiving, Most Merciful.

(134) Those who sustain the Throne (of Allah) and those around it Sing Glory and Praise to their Lord; believe in Him; and implore Forgiveness for those who believe: "Our Lord! Thy Reach is over all things, in mercy and Knowledge. Forgive, then, those who turn in Repentance, and follow Thy Path; and preserve them from the Penalty of the Blazing Fire!

(135) "And preserve them from (all) ills; and any whom Thou dost preserve from ills that Day,- on them wilt Thou have bestowed mercy indeed: and that will be truly (for them) the highest Achievement".

(136) So persevere in patience; for the Promise of Allah is true: and whether We show thee (in this life) some part of what We promise them,- or We take thy soul (to Our mercy) (before that),-(in any case) it is to Us that they shall (all) return.

(137) When we give him a taste of some mercy from Ourselves, after some adversity has touched him, he is sure to say, "This is due to my (merit): I think not that the Hour (of Judgment) will (ever) be established; but if I am brought back to my Lord, I have (much) good (stored) in His sight!" But We will show the Unbelievers the truth of all that they did, and We shall give them the taste of a severe Penalty.

(138) If Allah had so willed, He could have made them a single people; but He admits whom He will to His mercy; and the Wrong-doers will have no protector nor helper.

(139) He is the One that sends down rain (even) after (men) have given up all hope, and scatters His mercy (far and wide). And He is the Protector, Worthy of all Praise.

(140) If then they run away, We have not sent thee as a guard over them. Thy duty is but to convey (the Message). And truly, when We give man a taste of a mercy from Ourselves, he doth exult thereat, but when some ill happens to him, on account of the deeds which his hands have sent forth, truly then is man ungrateful!
