The word(s) "mercy" appears 168 time(s) in 158 verse(s) in Quran in Mohsin Khan translation.

(71) And if you (O Muhammad صلى الله عليه و سلم) turn away from them (kindred, poor, wayfarer whom We have ordered you to give their rights, but if you have no money at the time they ask you for it) and you are awaiting a mercy from your Lord for which you hope, then, speak unto them a soft kind word (i.e. Allah will give me and I shall give you).

(72) This is (part) of Al-Hikmah (wisdom, good manners and high character) which your Lord has revealed to you (O Muhammad صلى الله عليه و سلم). And set not up with Allah any other ilah (god) lest you should be thrown into Hell, blameworthy and rejected, (from Allah's mercy).

(73) Your Lord knows you best; if He wills, He will have mercy on you, or if He wills, He will punish you. And We have not sent you (O Muhammad صلى الله عليه و سلم) as a guardian over them.

(74) Those whom they call upon [like 'Îsa (Jesus) - son of Maryam (Mary), 'Uzair (Ezra), angel] desire (for themselves) means of access to their Lord (Allah), as to which of them should be the nearest; and they ['Îsa (Jesus), 'Uzair (Ezra), angels and others] hope for His mercy and fear His Torment. Verily, the Torment of your Lord is (something) to be afraid of!

(75) And We send down of the Qur'an that which is a healing and a mercy to those who believe (in Islamic Monotheism and act on it), and it increases the Zalimun (polytheists and wrong-doers) nothing but loss.

(76) Except as a mercy from your Lord. Verily His Grace unto you (O Muhammad صلى الله عليه و سلم) is ever great.

(77) Say (to the disbelievers): "If you possessed the treasure of the mercy of my Lord (wealth, money, provision.), then you would surely hold back (from spending) for fear of (being exhausted), and man is ever miserly!"

(78) (Remember) when the young men fled for refuge (from their disbelieving folk) to the Cave. They said: "Our Lord! Bestow on us mercy from Yourself, and facilitate for us our affair in the right way!"

(79) (The young men said to one another): "And when you withdraw from them, and that which they worship, except Allah, then seek refuge in the Cave; your Lord will open a way for you from His mercy and will make easy for you your affair (i.e. will give you what you will need of provision, dwelling)."

(80) And your Lord is Most Forgiving, Owner of mercy. Were He to call them to account for what they have earned, then surely, He would have hastened their punishment. But they have their appointed time, beyond which they will find no escape.
