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

(131) And We gave him (back) his family, and along with them the like thereof, as a mercy from Us, and a Reminder for those who understand.

(132) Is one who is obedient to Allah, prostrating himself or standing (in prayer) during the hours of the night, fearing the Hereafter and hoping for the mercy of his Lord (like one who disbelieves)? Say: "Are those who know equal to those who know not?" It is only men of understanding who will remember (i.e. get a lesson from Allah's Signs and Verses).

(133) And verily, if you ask them: "Who created the heavens and the earth?" Surely they will say: "Allah (has created them)." Say: "Tell me then, the things that you invoke besides Allah - if Allah intended some harm for me, could they remove His harm? Or if He (Allah) intended some mercy for me, could they withhold His mercy?" Say: "Sufficient for me is Allah; in Him those who trust (i.e. believers) must put their trust. "

(134) Say: "O 'Ibadi (My slaves) who have transgressed against themselves (by committing evil deeds and sins)! Despair not of the mercy of Allah: verily, Allah forgives all sins. Truly He is Oft-Forgiving, Most Merciful.

(135) Those (angels) who bear the Throne (of Allah) and those around it glorify the praises of their Lord, and believe in Him, and ask forgiveness for those who believe (in the Oneness of Allah) (saying): "Our Lord! You comprehend all things in mercy and knowledge, so forgive those who repent and follow Your Way, and save them from the torment of the blazing Fire!

(136) "And save them from (the punishment, for what they did of) the sins, and whomsoever You save from (the punishment for what he did of) the sins (i.e. pardon him) that Day, him verily, You have taken into mercy." And that is the supreme success.

(137) And truly, if We give him a taste of mercy from Us, after some adversity (severe poverty or disease, etc.) has touched him, he is sure to say: "This is due to my (merit); I think not that the Hour will be established. But if I am brought back to my Lord, surely, there will be for me the best (wealth) with Him. Then, We verily, will show to the disbelievers what they have done, and We shall make them taste a severe torment.

(138) And if Allah had willed, He could have made them one nation, but He admits whom He wills to His mercy. And the Zalimun (polytheists and wrong-doers) will have neither a Wali (protector or guardian) nor a helper.

(139) And He it is Who sends down the rain after they have despaired, and spreads His mercy. And He is the Wali (Helper, Supporter, Protector, Lord), Worthy of all Praise.

(140) But if they turn away (O Muhammad صلى الله عليه و سلم from the Islamic Monotheism, which you have brought to them). We have not sent you (O Muhammad صلى الله عليه و سلم) as a Hafiz (watcher, protector) over them (i.e. to take care of their deeds and to recompense them). Your duty is to convey (the Message). And verily, when We cause man to taste of mercy from Us, he rejoices thereat; but when some ill befalls them because of the deeds which their hands have sent forth, then verily, man (becomes) ingrate!
