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

(101) And had it not been for the Grace of Allah and His mercy on you, (Allah would have hastened the punishment upon you). And that Allah is full of Kindness, Most Merciful.

(102) O you who believe! Follow not the footsteps of Shaitan (Satan). And whosoever follows the footsteps of Shaitan (Satan), then, verily he commands Al-Fahsha' [i.e. to commit indecency (illegal sexual intercourse)], and Al-Munkar [disbelief and polytheism (i.e. to do evil and wicked deeds; and to speak or to do what is forbidden in Islam)]. And had it not been for the Grace of Allah and His mercy on you, not one of you would ever have been pure from sins. But Allah purifies (guides to Islam) whom He wills, and Allah is All-Hearer, All-Knower.

(103) And perform As-Salat (Iqamat-as-Salat), and give Zakat and obey the Messenger (Muhammad صلى الله عليه وسلم) that you may receive mercy (from Allah).

(104) And it is He Who sends the winds as heralds of glad tidings, going before His mercy (rain); and We send down pure water from the sky.

(105) So he [Sulaiman (Solomon)] smiled, amused at her speech and said: "My Lord! Grant me the power and ability that I may be grateful for Your Favours which You have bestowed on me and on my parents, and that I may do righteous good deeds that will please You, and admit me by Your mercy among Your righteous slaves."

(106) He said: "O my people! Why do you seek to hasten the evil (torment) before the good (Allah's mercy)? Why seek you not the Forgiveness of Allah, that you may receive mercy?"

(107) Is not He (better than your gods) Who guides you in the darkness of the land and the sea, and Who sends the winds as heralds of glad tidings, going before His mercy (rain)? Is there any ilah (god) with Allah? High Exalted be Allah above all that they associate as partners (to Him)!

(108) And truly, it (this Qur'an) is a guide and a mercy for the believers.

(109) And We made a curse to follow them in this world, and on the Day of Resurrection, they will be among Al-Maqbuhun (those who are prevented from receiving Allah's mercy or any good; despised or destroyed).

(110) And indeed We gave Musa (Moses) - after We had destroyed the generations of old -the Scripture [the Taurat (Torah)] as an enlightenment for mankind, and a guidance and a mercy, that they might remember (or receive admonition).
