The word(s) "easts" appears 43 time(s) in 41 verse(s) in Quran in Mohsin Khan translation.

(31) Or say they: "He has invented a lie against Allah?" If Allah willed, He could have sealed up your heart (so that you forget all that you know of the Qur'an). And Allah wipes out falsehood, and establishes the truth (Islam) by His Word (this Qur'an). Verily, He knows well what (secrets) are in the breasts (of mankind).

(32) Till, when (such a one) comes to Us, he says [to his Qarin (Satan / devil companion)] "Would that between me and you were the distance of the two easts (or the east and west)" - a worst (type of) companion (indeed)!

(33) (He is) the Lord of the two easts (places of sunrise during early summer and early winter) and the Lord of the two wests (places of sunset during early summer and early winter).

(34) He merges night into day (i.e. the decrease in the hours of the night is added into the hours of the day), and merges day into night (i.e. the decrease in the hours of the day is added into the hours of the night), and He has full knowledge of whatsoever is in the breasts.

(35) And (it is also for) those who, before them, had homes (in Al-Madinah) and had adopted the Faith, love those who emigrate to them, and have no jealousy in their breasts for that which they have been given (from the booty of Banu An-Nadir), and give them (emigrants) preference over themselves even though they were in need of that. And whosoever is saved from his own covetousness, such are they who will be the successful.

(36) Verily, you (believers in the Oneness of Allah - Islamic Monotheism) are more fearful in their (Jews of Banu An-Nadir) breasts than Allah. That is because they are a people who comprehend not (the Majesty and Power of Allah).

(37) He knows what is in the heavens and on earth, and He knows what you conceal and what you reveal. And Allah is the All-Knower of what is in the breasts (of men).

(38) And whether you keep your talk secret or disclose it, Verily, He is the All-Knower of what is in the breasts (of men).

(39) And when the wild beasts are gathered together.

(40) And that which is in the breasts (of men) is made known?
