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

(21) Say: Unto whom belongeth whatsoever is in the heavens and the earth? Say: Unto Allah. He hath prescribed for Himself mercy, that He may bring you all together to the Day of Resurrection whereof there is no doubt. Those who ruin their souls will not believe.

(22) He from whom (such retribution) is averted on that day, (Allah) hath in truth had mercy on him. That will be the signal triumph.

(23) And when those who believe in Our revelations come unto thee, say: Peace be unto you! Your Lord hath prescribed for Himself mercy, that whoso of you doeth evil through ignorance and repenteth afterward thereof and doeth right, (for him) lo! He is Forgiving, Merciful.

(24) Thy Lord is the Absolute, the Lord of mercy. If He will, He can remove you and can cause what He will to follow after you, even as He raised you from the seed of other folk.

(25) So if they give the lie to thee (Muhammad), say: Your Lord is a Lord of All-Embracing mercy, and His wrath will never be withdrawn from guilty folk.

(26) Again, We gave the Scripture unto Moses, complete for him who would do good, an explanation of all things, a guidance and a mercy, that they might believe in the meeting with their Lord.

(27) And this is a blessed Scripture which We have revealed. So follow it and ward off (evil), that ye may find mercy.

(28) Or lest ye should say: If the Scripture had been revealed unto us, we surely had been better guided than are they. Now hath there come unto you a clear proof from your Lord, a guidance and mercy; and who doeth greater wrong than he who denieth the revelations of Allah, and turneth away from them? We award unto those who turn away from Our revelations an evil doom because of their aversion.

(29) They said: Our Lord! We have wronged ourselves. If thou forgive us not and have not mercy on us, surely we are of the lost!

(30) Are these they of whom ye swore that Allah would not show them mercy? (Unto them it hath been said): Enter the Garden. No fear shall come upon you nor is it ye who will grieve.
