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

(141) Then, as for those who believed and did good works, their Lord will bring them in unto His mercy. That is the evident triumph.

(142) When before it there was the Scripture of Moses, an example and a mercy; and this is a confirming Scripture in the Arabic language, that it may warn those who do wrong and bring good tidings for the righteous.

(143) These it was who disbelieved and debarred you from the Inviolable Place of Worship, and debarred the offering from reaching its goal. And if it had not been for believing men and believing women, whom ye know not - lest ye should tread them under foot and thus incur guilt for them unknowingly; that Allah might bring into His mercy whom He will - If (the believers and the disbelievers) had been clearly separated We verily had punished those of them who disbelieved with painful punishment.

(144) The believers are naught else than brothers. Therefore make peace between your brethren and observe your duty to Allah that haply ye may obtain mercy.

(145) Those who avoid enormities of sin and abominations, save the unwilled offences - (for them) lo! thy Lord is of vast mercy. He is Best Aware of you (from the time) when He created you from the earth, and when ye were hidden in the bellies of your mothers. Therefor ascribe not purity unto yourselves. He is Best Aware of him who wardeth off (evil).

(146) On the day when the hypocritical men and the hypocritical women will say unto those who believe: Look on us that we may borrow from your light! it will be said: Go back and seek for light! Then there will separate them a wall wherein is a gate, the inner side whereof containeth mercy, while the outer side thereof is toward the doom.

(147) Then We caused Our messengers to follow in their footsteps; and We caused Jesus, son of Mary, to follow, and gave him the Gospel, and placed compassion and mercy in the hearts of those who followed him. But monasticism they invented - We ordained it not for them - only seeking Allah's pleasure, and they observed it not with right observance. So We give those of them who believe their reward, but many of them are evil-livers.

(148) O ye who believe! Be mindful of your duty to Allah and put faith in His messenger. He will give you twofold of His mercy and will appoint for you a light wherein ye shall walk, and will forgive you. Allah is Forgiving, Merciful;

(149) So they acknowledge their sins; but far removed (from mercy) are the dwellers in the flames.

(150) Say (O Muhammad): Have ye thought: Whether Allah causeth me (Muhammad) and those with me to perish or hath mercy on us, still, who will protect the disbelievers from a painful doom?
