The word(s) "ease" appears 176 time(s) in 154 verse(s) in Quran in Mohsin Khan translation.

(81) Then High above all be Allah, the True King. And be not in haste (O Muhammad صلى الله عليه وسلم) with the Qur'an before its revelation is completed to you, and say: "My Lord! Increase me in knowledge."

(82) So bear patiently (O Muhammad صلى الله عليه وسلم) what they say, and glorify the praises of your Lord before the rising of the sun, and before its setting, and during some hours of the night, and at the ends of the day (an indication for the five compulsory congregational prayers), that you may become pleased (with the reward which Allah shall give you).

(83) And that cry of theirs ceased not, till We made them as a field that is reaped, extinct (dead).

(84) He knows what is before them, and what is behind them, and they cannot intercede except for him with whom He is pleased. And they stand in awe for fear of Him.

(85) That He (Allah) may make what is thrown in by Shaitan (Satan) a trial for those in whose hearts is a disease (of hypocrisy and disbelief) and whose hearts are hardened. And certainly, the Zalimun (polytheists and wrong-doers) are in an opposition far-off (from the truth against Allah's Messenger and the believers).

(86) And those who disbelieved will not cease to be in doubt about it (this Qur'an) until the Hour comes suddenly upon them, or there comes to them the torment of the Day after which there will be no night (i.e. the Day of Resurrection).

(87) Truly, He will make them enter an entrance with which they shall be well-pleased, and verily, Allah indeed is All-Knowing, Most Forbearing.

(88) O mankind! A similitude has been coined, so listen to it (carefully): Verily those on whom you call besides Allah, cannot create (even) a fly, even though they combine together for the purpose. And if the fly snatches away a thing from them, they will have no power to release it from the fly. So weak are (both) the seeker and the sought.

(89) Is there a disease in their hearts? Or do they doubt or fear lest Allah and His Messenger (صلى الله عليه وسلم) should wrong them in judgement. Nay, it is they themselves who are the Zalimun (polytheists, hypocrites and wrong-doers).

(90) And when it is said to them: "Prostrate yourselves to the Most Gracious (Allah)! they say: "And what is the Most Gracious? Shall we fall down in prostration to that which you (O Muhammad صلى الله عليه وسلم) command us?" And it increases in them only aversion.
