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

(51) But no! by your Lord! they do not believe (in reality) until they make you a judge of that which has become a matter of disagreement among them, and then do not find any straitness in their hearts as to what you have decided and submit with entire submission.

(52) And they say: Obedience. But when they go out from your presence, a party of them decide by night upon doing otherwise than what you say; and Allah writes down what they decide by night, therefore turn aside from them and trust in Allah, and Allah is sufficient as a protector.

(53) What is the matter with you, then, that you have become two parties about the hypocrites, while Allah has made them return (to unbelief) for what they have earned? Do you wish to guide him whom Allah has caused to err? And whomsoever Allah causes to err, you shall by no means find a way for him.

(54) And it does not behoove a believer to kill a believer except by mistake, and whoever kills a believer by mistake, he should free a believing slave, and blood-money should be paid to his people unless they remit it as alms; but if he be from a tribe hostile to you and he is a believer, the freeing of a believing slave (suffices), and if he is from a tribe between whom and you there is a convenant, the blood-money should be paid to his people along with the freeing of a believing slave; but he who cannot find (a slave) should fast for two months successively: a penance from Allah, and Allah is Knowing, Wise.

(55) Surely We have revealed the Book to you with the truth that you may judge between people by means of that which Allah has taught you; and be not an advocate on behalf of the treacherous.

(56) They hide themselves from men and do not hide themselves from Allah, and He is with them when they meditate by night words which please Him not, and Allah encompasses what they do.

(57) Those who wait for (some misfortune to befall) you then If you have a victory from Allah they say: Were we not with you? And if there is a chance for the unbelievers, they say: Did we not acquire the mastery over you and defend you from the believers? So Allah shall Judge between you on the day of resurrection, and Allah will by no means give the unbelievers a way against the believers.

(58) Allah does not love the public utterance of hurtful speech unless (it be) by one to whom injustice has been done; and Allah is Hearing, Knowing.

(59) But Allah bears witness by what He has revealed to you that He has revealed it with His knowledge, and the angels bear witness (also); and Allah is sufficient as a witness.

(60) The Messiah does by no means disdain that he should be a servant of Allah, nor do the angels who are near to Him, and whoever disdains His service and is proud, He will gather them all together to Himself.
