The word(s) "by" appears 593 time(s) in 514 verse(s) in Quran in Abdullah Yusuf Ali translation.

(181) Said one of them: "Slay not Joseph, but if ye must do something, throw him down to the bottom of the well: he will be picked up by some caravan of travellers."

(182) "Then will come after that (period) seven dreadful (years), which will devour what ye shall have laid by in advance for them,- (all) except a little which ye shall have (specially) guarded.

(183) Further he said: "O my sons! enter not all by one gate: enter ye by different gates. Not that I can profit you aught against Allah (with my advice): None can command except Allah: On Him do I put my trust: and let all that trust put their trust on Him."

(184) And when they entered in the manner their father had enjoined, it did not profit them in the least against (the plan of) Allah: It was but a necessity of Jacob's soul, which he discharged. For he was, by our instruction, full of knowledge (and experience): but most men know not.

(185) They said: "We miss the great beaker of the king; for him who produces it, is (the reward of) a camel load; I will be bound by it."

(186) (The brothers) said: "by Allah! well ye know that we came not to make mischief in the land, and we are no thieves!"

(187) So he began (the search) with their baggage, before (he came to) the baggage of his brother: at length he brought it out of his brother's baggage. Thus did We plan for Joseph. He could not take his brother by the law of the king except that Allah willed it (so). We raise to degrees (of wisdom) whom We please: but over all endued with knowledge is one, the All-Knowing.

(188) They said: "by Allah! (never) wilt thou cease to remember Joseph until thou reach the last extremity of illness, or until thou die!"

(189) They said: "by Allah! indeed has Allah preferred thee above us, and we certainly have been guilty of sin!"

(190) They said: "by Allah! truly thou art in thine old wandering mind."
