The word(s) "by" appears 750 time(s) in 615 verse(s) in Quran in Mohsin Khan translation.

(321) Say: "It (this Qur'an) has been sent down by Him (Allah) (the Real Lord of the heavens and earth) Who knows the secret of the heavens and the earth. Truly, He is Oft-Forgiving, Most Merciful."

(322) And those who disbelieve say: "Why is not the Qur'an revealed to him all at once?" Thus (it is sent down in parts), that We may strengthen your heart thereby. And We have revealed it to you gradually, in stages. (It was revealed to the Prophet صلى الله عليه وسلم in 23 years.).

(323) And indeed they have passed by the town [of Prophet Lut (Lot)] on which was rained the evil rain. Did they (disbelievers) not then see it (with their own eyes)? Nay! But they used not to expect any resurrection.

(324) That We may give life thereby to a dead land, and We give to drink thereof many of the cattle and men that We had created.

(325) So obey not the disbelievers, but strive against them (by preaching) with the utmost endeavour with it (the Qur'an).

(326) And it is He Who has created man from water, and has appointed for him kindred by blood, and kindred by marriage. And your Lord is Ever All-Powerful to do what He wills.

(327) And those who do not bear witness to falsehood, and if they pass by some evil play or evil talk, they pass by it with dignity.

(328) These are the Verses of the manifest Book [(this Qur'an), which was promised by Allah in the Taurat (Torah) and the Injeel (Gospel), makes things clear].

(329) "He wants to drive you out of your land by his sorcery: what is it then that you command?"

(330) So they threw their ropes and their sticks, and said: "by the might of Fir'aun (Pharaoh), it is we who will certainly win!"
