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

(291) Musa (Moses) said to them: "Woe unto you! Invent not a lie against Allah, lest He should destroy you completely by a torment. And surely, he who invents a lie (against Allah) will fail miserably."

(292) [Musa (Moses)] said: "Nay, throw you (first)!" Then behold! their ropes and their sticks, by their magic, appeared to him as though they moved fast.

(293) 'Adn (Eden) Paradise (everlasting Gardens), under which rivers flow, wherein they will abide forever: such is the reward of those who purify themselves (by abstaining from all kinds of sins and evil deeds which Allah has forbidden and by doing all that Allah has ordained).

(294) And indeed We revealed to Musa (Moses) (saying): "Travel by night with Ibadi (My slaves) and strike a dry path for them in the sea, fearing neither to be overtaken [by Fir'aun (Pharaoh)] nor being afraid (of drowning in the sea)."

(295) He [Harun (Aaron)] said: "O son of my mother! Seize (me) not by my beard, nor by my head! Verily, I feared lest you should say: 'You have caused a division among the Children of Israel, and you have not respected my word!' "

(296) And strain not your eyes in longing for the things We have given for enjoyment to various groups of them (polytheists and disbelievers in the Oneness of Allah), the splendour of the life of this world, that We may test them thereby. But the provision (good reward in the Hereafter) of your Lord is better and more lasting.

(297) Then We fulfilled to them the promise. So We saved them and those whom We willed, but We destroyed Al-Musrifun (i.e. disbelievers in Allah, in His Messengers, extravagants, transgressors of Allah's limits by committing crimes, oppressions, polytheism and sins).

(298) Nay, We fling (send down) the truth (this Qur'an) against the falsehood (disbelief), so it destroys it, and behold, it (falsehood) is vanished. And woe to you for that (lie) which you ascribe (to Allah by uttering that Allah has a wife and a son).

(299) Indeed, (many) Messengers were mocked before you (O Muhammad صلى الله عليه وسلم), but the scoffers were surrounded by that, whereat they used to mock.

(300) Say (O Muhammad صلى الله عليه وسلم): "I warn you only by the revelation (from Allah and not by the opinion of the religious scholars and others). But the deaf (who follow the religious scholars and others blindly) will not hear the call, (even) when they are warned [i.e. one should follow only the Qur'an and the Sunnah (legal ways, orders, acts of worship, and the statements of Prophet Muhammad صلى الله عليه وسلم, as the companions of the Prophet صلى الله عليه وسلم did)] .
