The word(s) "ease" appears 198 time(s) in 166 verse(s) in Quran in Abdullah Yusuf Ali translation.

(131) Gracious is Allah to His servants: He gives Sustenance to whom He pleases: and He has power and can carry out His Will.

(132) To any that desires the tilth of the Hereafter, We give increase in his tilth, and to any that desires the tilth of this world, We grant somewhat thereof, but he has no share or lot in the Hereafter.

(133) That is (the Bounty) whereof Allah gives Glad Tidings to His Servants who believe and do righteous deeds. Say: "No reward do I ask of you for this except the love of those near of kin." And if any one earns any good, We shall give him an increase of good in respect thereof: for Allah is Oft-Forgiving, Most Ready to appreciate (service).

(134) And He listens to those who believe and do deeds of righteousness, and gives them increase of His Bounty: but for the Unbelievers their is a terrible Penalty.

(135) If Allah were to enlarge the provision for His Servants, they would indeed transgress beyond all bounds through the earth; but he sends (it) down in due measure as He pleases. For He is with His Servants Well-acquainted, Watchful.

(136) But to those who receive Guidance, He increases the (light of) Guidance, and bestows on them their Piety and Restraint (from evil).

(137) Those who believe say, "Why is not a sura sent down (for us)?" But when a sura of basic or categorical meaning is revealed, and fighting is mentioned therein, thou wilt see those in whose hearts is a disease looking at thee with a look of one in swoon at the approach of death. But more fitting for them-

(138) Or do those in whose hearts is a disease, think that Allah will not bring to light all their rancour?

(139) And those that flow with ease and gentleness;

(140) They will recline (with ease) on Thrones (of dignity) arranged in ranks; and We shall join them to Companions, with beautiful big and lustrous eyes.
