The word(s) "east" appears 92 time(s) in 88 verse(s) in Quran in Mohsin Khan translation.

(31) Fight against them so that Allah will punish them by your hands and disgrace them and give you victory over them and heal the breasts of a believing people,

(32) O mankind! There has come to you a good advice from your Lord (i.e. the Qur'an, enjoining all that is good and forbidding all that is evil), and a healing for that (disease of ignorance, doubt, hypocrisy and differences) which is in your breasts, - a guidance and a mercy (explaining lawful and unlawful things) for the believers.

(33) No doubt! They did fold up their breasts, that they may hide from Him. Surely, even when they cover themselves with their garments, He knows what they conceal and what they reveal. Verily, He is the All-Knower of the (innermost secrets) of the breasts.

(34) So perchance you (Muhammad صلى الله عليه و سلم) may give up a part of what is revealed unto you, and that your breast feels straitened for it because they say, "Why has not a treasure been sent down unto him, or an angel has come with him?" But you are only a warner. And Allah is a Wakil (Disposer of affairs, Trustee, Guardian) over all things.

(35) "So if you turn away, still I have conveyed the Message with which I was sent to you. My Lord will make another people succeed you, and you will not harm Him in the least. Surely, my Lord is Guardian over all things."

(36) And when they entered according to their father's advice, it did not avail them in the least against (the Will of) Allah; it was but a need of Ya'qub's (Jacob) inner-self which he discharged. And verily, he was endowed with knowledge because We had taught him, but most men know not.

(37) And We have provided therein means of living, for you and for those whom you provide not [moving (living) creatures, cattle, beasts, and other animals].

(38) "And We shall remove from their breasts any deep feeling of bitterness (that they may have). (So they will be like) brothers facing each other on thrones.

(39) Indeed, We know that your breast is straitened at what they say.

(40) Whoever disbelieved in Allah after his belief, except him who is forced thereto and whose heart is at rest with Faith; but such as open their breasts to disbelief, on them is wrath from Allah, and theirs will be a great torment.
