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

(121) A guidance and a mercy for the good,

(122) Say: Who is he who can preserve you from Allah if He intendeth harm for you, or intendeth mercy for you. They will not find that they have any friend or helper other than Allah.

(123) That which Allah openeth unto mankind of mercy none can withhold it; and that which He withholdeth none can release thereafter. He is the Mighty, the Wise.

(124) Unless by mercy from Us and as comfort for a while.

(125) When it is said unto them: Beware of that which is before you and that which is behind you, that haply ye may find mercy (they are heedless).

(126) Or are theirs the treasures of the mercy of thy Lord, the Mighty, the Bestower?

(127) And We bestowed on him (again) his household and therewith the like thereof, a mercy from Us, and a memorial for men of understanding.

(128) Is he who payeth adoration in the watches of the night, prostrate and standing, bewaring of the Hereafter and hoping for the mercy of his Lord, (to be accounted equal with a disbeliever)? Say (unto them, O Muhammad): Are those who know equal with those who know not? But only men of understanding will pay heed.

(129) And verily, if thou shouldst ask them: Who created the heavens and the earth? they will say: Allah. Say: Bethink you then of those ye worship beside Allah, if Allah willed some hurt for me, could they remove from me His hurt; or if He willed some mercy for me, could they restrain His mercy? Say: Allah is my all. In Him do (all) the trusting put their trust.

(130) Say: O My slaves who have been prodigal to their own hurt! Despair not of the mercy of Allah, Who forgiveth all sins. Lo! He is the Forgiving, the Merciful.
