The word(s) "by" appears 450 time(s) in 398 verse(s) in Quran in Muhammad Habib Shakir translation.

(301) Yet they turned their backs on him and said: One taught (by others), a madman.

(302) So go forth with My servants by night; surely you will be pursued:

(303) And (in) the variation of the night and the day, and (in) what Allah sends down of sustenance from the cloud, then gives life thereby to the earth after its death, and (in) the changing of the winds, there are signs for a people who understand.

(304) Allah is He Who made subservient to you the sea that the ships may run therein by His command, and that you may seek of His grace, and that you may give thanks.

(305) And those who disbelieve say concerning those who believe: If it had been a good, they would not have gone ahead of us therein. And as they do not seek to be rightly directed thereby, they say: It is an old lie.

(306) Destroying everything by the command of its Lord, so they became such that naught could be seen except their dwellings. Thus do We reward the guilty people.

(307) Have they not considered that Allah, Who created the heavens and the earth and was not tired by their creation, is able to give life to the dead? Aye! He has surely power over all things.

(308) And on the day when those who disbelieve shall be brought before the fire: Is it not true? They shall say: Aye! by our Lord! He will say: Then taste the punishment, because you disbelieved.

(309) So when you meet in battle those who disbelieve, then smite the necks until when you have overcome them, then make (them) prisoners, and afterwards either set them free as a favor or let them ransom (themselves) until the war terminates. That (shall be so); and if Allah had pleased He would certainly have exacted what is due from them, but that He may try some of you by means of others; and (as for) those who are slain in the way of Allah, He will by no means allow their deeds to perish.

(310) And if We please We would have made you know them so that you would certainly have recognized them by their marks and most certainly you can recognize them by the intent of (their) speech; and Allah knows your deeds.
