The word(s) "by" appears 439 time(s) in 392 verse(s) in Quran in Muhammad Pickthal translation.

(281) Verily We sent messengers before thee, among them those of whom We have told thee, and some of whom We have not told thee; and it was not given to any messenger that he should bring a portent save by Allah's leave, but when Allah's commandment cometh (the cause) is judged aright, and the followers of vanity will then be lost.

(282) (Many) benefits ye have from them - and that ye may satisfy by their means a need that is in your breasts, and may be borne upon them as upon the ship.

(283) The Creator of the heavens and the earth. He hath made for you pairs of yourselves, and of the cattle also pairs, whereby He multiplieth you. Naught is as His likeness; and He is the Hearer, the Seer.

(284) Or say they: He hath invented a lie concerning Allah? If Allah willed, He could have sealed thy heart (against them). And Allah will wipe out the lie and will vindicate the truth by His words. Lo! He is Aware of what is hidden in the breasts (of men).

(285) And if Allah were to enlarge the provision for His slaves they would surely rebel in the earth, but He sendeth down by measure as He willeth. Lo! He is Informed, a Seer of His bondmen.

(286) And thou wilt see them exposed to (the Fire), made humble by disgrace, and looking with veiled eyes. And those who believe will say: Lo! the (eternal) losers are they who lose themselves and their housefolk on the Day of Resurrection. Lo! are not the wrong-doers in perpetual torment?

(287) And it was not (vouchsafed) to any mortal that Allah should speak to him unless (it be) by revelation or from behind a veil, or (that) He sendeth a messenger to reveal what He will by His leave. Lo! He is Exalted, Wise.

(288) And thus have We inspired in thee (Muhammad) a Spirit of Our command. Thou knewest not what the Scripture was, nor what the Faith. But We have made it a light whereby We guide whom We will of Our bondmen. And lo! thou verily dost guide unto a right path,

(289) by the Scripture which maketh plain,

(290) Nay, for they say only: Lo! we found our fathers following a religion, and we are guided by their footprints.
