The word(s) "mercy" appears 164 time(s) in 155 verse(s) in Quran in Muhammad Pickthal translation.

(81) When the young men fled for refuge to the Cave and said: Our Lord! Give us mercy from Thy presence, and shape for us right conduct in our plight.

(82) And when ye withdraw from them and that which they worship except Allah, then seek refuge in the Cave; your Lord will spread for you of His mercy and will prepare for you a pillow in your plight.

(83) Thy Lord is the Forgiver, Full of mercy. If He took them to task (now) for what they earn, He would hasten on the doom for them; but theirs is an appointed term from which they will find no escape.

(84) Then found they one of Our slaves, unto whom We had given mercy from Us, and had taught him knowledge from Our presence.

(85) And we intended that their Lord should change him for them for one better in purity and nearer to mercy.

(86) And as for the wall, it belonged to two orphan boys in the city, and there was beneath it a treasure belonging to them, and their father had been righteous, and thy Lord intended that they should come to their full strength and should bring forth their treasure as a mercy from their Lord; and I did it not upon my own command. Such is the interpretation of that wherewith thou couldst not bear.

(87) He said: This is a mercy from my Lord; but when the promise of my Lord cometh to pass, He will lay it low, for the promise of my Lord is true.

(88) A mention of the mercy of thy Lord unto His servant Zachariah.

(89) He said: So (it will be). Thy Lord saith: It is easy for Me. And (it will be) that We may make of him a revelation for mankind and a mercy from Us, and it is a thing ordained.

(90) And we gave them of Our mercy, and assigned to them a high and true renown.
