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

(131) Those who bear the Throne, and all who are round about it, hymn the praises of their Lord and believe in Him and ask forgiveness for those who believe (saying): Our Lord! Thou comprehendest all things in mercy and knowledge, therefor forgive those who repent and follow Thy way. Ward off from them the punishment of hell.

(132) And ward off from them ill-deeds; and he from whom Thou wardest off ill-deeds that day, him verily hast Thou taken into mercy. That is the supreme triumph.

(133) And verily, if We cause him to taste mercy after some hurt that hath touched him, he will say: This is my own; and I deem not that the Hour will ever rise, and if I am brought back to my Lord, I surely shall be better off with Him - But We verily shall tell those who disbelieve (all) that they did, and We verily shall make them taste hard punishment.

(134) Had Allah willed, He could have made them one community, but Allah bringeth whom He will into His mercy. And the wrong-doers have no friend nor helper.

(135) And He it is Who sendeth down the saving rain after they have despaired, and spreadeth out His mercy. He is the Protecting Friend, the Praiseworthy.

(136) But if they are averse, We have not sent thee as a warder over them. Thine is only to convey (the message). And lo! when We cause man to taste of mercy from Us he exulteth therefor. And if some evil striketh them because of that which their own hands have sent before, then lo! man is an ingrate.

(137) Is it they who apportion thy Lord's mercy? We have apportioned among them their livelihood in the life of the world, and raised some of them above others in rank that some of them may take labour from others; and the mercy of thy Lord is better than (the wealth) that they amass.

(138) A mercy from thy Lord. Lo! He, even He is the Hearer, the Knower,

(139) Save him on whom Allah hath mercy. Lo! He is the Mighty, the Merciful.

(140) This is clear indication for mankind, and a guidance and a mercy for a folk whose faith is sure.
