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

(101) Had it not been for the grace of Allah and His mercy unto you in the world and the Hereafter an awful doom had overtaken you for that whereof ye murmured.

(102) Had it not been for the grace of Allah and His mercy unto you, and that Allah is Clement, Merciful, (ye had been undone).

(103) O ye who believe! Follow not the footsteps of the devil. Unto whomsoever followeth the footsteps of the devil, lo! he commandeth filthiness and wrong. Had it not been for the grace of Allah and His mercy unto you, not one of you would ever have grown pure. But Allah causeth whom He will to grow. And Allah is Hearer, Knower.

(104) Establish worship and pay the poor-due and obey the messenger, that haply ye may find mercy.

(105) And He it is Who sendeth the winds, glad tidings heralding His mercy, and We send down purifying water from the sky,

(106) He said: O my people! Why will ye hasten on the evil rather than the good? Why will ye not ask pardon of Allah, that ye may receive mercy.

(107) Is not He (best) Who guideth you in the darkness of the land and the sea, He Who sendeth the winds as heralds of His mercy? Is there any Allah beside Allah? High Exalted be Allah from all that they ascribe as partner (unto Him)!

(108) And lo! it is a guidance and a mercy for believers.

(109) And We verily gave the Scripture unto Moses after We had destroyed the generations of old: clear testimonies for mankind, and a guidance and a mercy, that haply they might reflect.

(110) And thou was not beside the Mount when We did call; but (the knowledge of it is) a mercy from thy Lord that thou mayst warn a folk unto whom no warner came before thee, that haply they may give heed.
