The word(s) "mercy" appears 164 time(s) in 156 verse(s) in Quran in Abdullah Yusuf Ali translation.

(121) A Guide and a mercy to the Doers of Good,-

(122) Say: "Who is it that can screen you from Allah if it be His wish to give you punishment or to give you mercy?" Nor will they find for themselves, besides Allah, any protector or helper.

(123) That Allah may reward the men of Truth for their Truth, and punish the Hypocrites if that be His Will, or turn to them in mercy: for Allah is Oft-Forgiving, Most Merciful.

(124) He it is Who sends blessings on you, as do His angels, that He may bring you out from the depths of Darkness into Light: and He is Full of mercy to the Believers.

(125) They shall have a curse on them: whenever they are found, they shall be seized and slain (without mercy).

(126) (With the result) that Allah has to punish the Hypocrites, men and women, and the Unbelievers, men and women, and Allah turns in mercy to the Believers, men and women: for Allah is Oft-Forgiving, Most Merciful.

(127) What Allah out of his mercy doth bestow on mankind there is none can withhold: what He doth withhold, there is none can grant, apart from Him: and He is the Exalted in Power, full of Wisdom.

(128) Except by way of mercy from Us, and by way of (world) convenience (to serve them) for a time.

(129) When they are told, "Fear ye that which is before you and that which will be after you, in order that ye may receive mercy," (they turn back).

(130) How many generations before them did We destroy? In the end they cried (for mercy)- when there was no longer time for being saved!
