The word(s) "merciful" appears 118 time(s) in 117 verse(s) in Quran in Abdullah Yusuf Ali translation.

(111) Allah is He, than Whom there is no other god;- Who knows (all things) both secret and open; He, Most Gracious, Most merciful.

(112) It may be that Allah will grant love (and friendship) between you and those whom ye (now) hold as enemies. For Allah has power (over all things); And Allah is Oft-Forgiving, Most merciful.

(113) O Prophet! When believing women come to thee to take the oath of fealty to thee, that they will not associate in worship any other thing whatever with Allah, that they will not steal, that they will not commit adultery (or fornication), that they will not kill their children, that they will not utter slander, intentionally forging falsehood, and that they will not disobey thee in any just matter,- then do thou receive their fealty, and pray to Allah for the forgiveness (of their sins): for Allah is Oft-Forgiving, Most merciful.

(114) O ye who believe! Truly, among your wives and your children are (some that are) enemies to yourselves: so beware of them! But if ye forgive and overlook, and cover up (their faults), verily Allah is Oft-Forgiving, Most merciful.

(115) O Prophet! Why holdest thou to be forbidden that which Allah has made lawful to thee? Thou seekest to please thy consorts. But Allah is Oft-Forgiving, Most merciful.

(116) Nay, who is there that can help you, (even as) an army, besides (Allah) Most merciful? In nothing but delusion are the Unbelievers.

(117) Thy Lord doth know that thou standest forth (to prayer) nigh two-thirds of the night, or half the night, or a third of the night, and so doth a party of those with thee. But Allah doth appoint night and day in due measure He knoweth that ye are unable to keep count thereof. So He hath turned to you (in mercy): read ye, therefore, of the Qur'an as much as may be easy for you. He knoweth that there may be (some) among you in ill-health; others travelling through the land, seeking of Allah's bounty; yet others fighting in Allah's Cause, read ye, therefore, as much of the Qur'an as may be easy (for you); and establish regular Prayer and give regular Charity; and loan to Allah a Beautiful Loan. And whatever good ye send forth for your souls ye shall find it in Allah's Presence,- yea, better and greater, in Reward and seek ye the Grace of Allah: for Allah is Oft-Forgiving, Most merciful.
