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

(401) So, the evil results of that which they earned overtook them. And those who did wrong of these [people to whom you (Muhammad صلى الله عليه وسلم) have been sent] will also be overtaken by the evil results (torment) for that which they earned; and they will never be able to escape.

(402) Say: "O 'Ibadi (My slaves) who have transgressed against themselves (by committing evil deeds and sins)! Despair not of the Mercy of Allah: verily, Allah forgives all sins. Truly He is Oft-Forgiving, Most Merciful.

(403) They made not a just estimate of Allah such as is due to Him. And on the Day of Resurrection the whole of the earth will be grasped by His Hand and the heavens will be rolled up in His Right Hand.Glorified be He, and High be He above all that they associate as partners with Him!

(404) The people of Nuh (Noah) and the Confederates after them denied (their Messengers) before these; and every (disbelieving) nation plotted against their Messenger to seize him, and disputed by means of falsehood to refute therewith the truth. So I seized them (with punishment), and how (terrible) was My punishment!

(405) It is He Who shows you His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) and sends down (rain with which grows) provision for you from the sky. And none remembers but those who turn (to Allah in obedience and) in repentance (by begging His Pardon and by worshipping and obeying Him Alone and none else).

(406) So, call you (O Muhammad صلى الله عليه وسلم and the believers) upon (or invoke) Allah making (your) worship pure for Him (Alone) (by worshipping none but Him and by doing religious deeds sincerely for Allah's sake only and not to show off and not to set up rivals with Him in worship), however much the disbelievers (in the Oneness of Allah) may hate (it).

(407) (He is Allah) Owner of High Ranks and Degrees, the Owner of the Throne. He sends the revelation by His Command to any of His slaves He wills, that he (the person who receives revelation) may warn (men) of the Day of Mutual Meeting (i.e. the Day of Resurrection).

(408) And indeed Yusuf (Joseph) did come to you, in times gone by, with clear signs, but you ceased not to doubt in that which he did bring to you: till when he died you said: "No Messenger will Allah send after him." Thus Allah leaves astray him who is a Musrif (a polytheist, an oppressor, a criminal, sinner who commit great sins) and a Murtab (one who doubts Allah's Warning and His Oneness).

(409) They will say: "Did there not come to you, your Messengers with (clear) evidence (and signs)?" They will say: "Yes." They will reply: "Then call (as you like)! And the invocation of the disbelievers is nothing but in vain (as it will not be answered by Allah)!"

(410) That is Allah, your Lord, the Creator of all things: La ilaha illa Huwa (none has the right to be worshipped but He). How then are you turning away (from Allah, by worshipping others instead of Him)?
