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

(21) Mankind were one community and Allah sent Prophets with glad tidings and warnings, and with them He sent down the Scripture in truth to judge between people in matters wherein they differed. And only those to whom (the Scripture) was given differed concerning it after clear proofs had come unto them through hatred, one to another. Then Allah by His Leave guided those who believed to the truth of that wherein they differed. And Allah guides whom He wills to the Straight Path.

(22) And do not marry Al-Mushrikat (idolatresses, etc.) till they believe (worship Allah Alone). And indeed a slave woman who believes is better than a (free) Mushrikah (idolatress), even though she pleases you. And give not (your daughters) in marriage to Al-Mushrikun till they believe (in Allah Alone) and verily, a believing slave is better than a (free) Mushrik (idolater), even though he pleases you. Those (Al-Mushrikun) invite you to the Fire, but Allah invites (you) to Paradise and Forgiveness by His Leave, and makes His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) clear to mankind that they may remember.

(23) They ask you concerning menstruation. Say: that is an Adha (a harmful thing for a husband to have a sexual intercourse with his wife while she is having her menses), therefore keep away from women during menses and go not unto them till they are purified (from menses and have taken a bath). And when they have purified themselves, then go in unto them as Allah has ordained for you (go in unto them in any manner as long as it is in their vagina). Truly, Allah loves those who turn unto Him in repentance and loves those who purify themselves (by taking a bath and cleaning and washing thoroughly their private parts, bodies, for their prayers).

(24) The divorce is twice, after that, either you retain her on reasonable terms or release her with kindness. And it is not lawful for you (men) to take back (from your wives) any of your Mahr (bridal-money given by the husband to his wife at the time of marriage) which you have given them, except when both parties fear that they would be unable to keep the limits ordained by Allah (e.g. to deal with each other on a fair basis). Then if you fear that they would not be able to keep the limits ordained by Allah, then there is no sin on either of them if she gives back (the Mahr or a part of it) for her Al-Khul' (divorce) . These are the limits ordained by Allah, so do not transgress them. And whoever transgresses the limits ordained by Allah, then such are the Zalimun (wrong-doers).

(25) And if he has divorced her (the third time), then she is not lawful unto him thereafter until she has married another husband. Then, if the other husband divorces her, it is no sin on both of them that they reunite, provided they feel that they can keep the limits ordained by Allah. These are the limits of Allah, which He makes plain for the people who have knowledge.

(26) And when you have divorced women and they have fulfilled the term of their prescribed period, either take them back on reasonable basis or set them free on reasonable basis. But do not take them back to hurt them, and whoever does that, then he has wronged himself. And treat not the Verses (Laws) of Allah as a jest, but remember Allah's Favours on you (i.e. Islam), and that which He has sent down to you of the Book (i.e. the Qur'an) and Al-Hikmah (the Prophet's Sunnah - legal ways - Islamic jurisprudence.) whereby He instructs you. And fear Allah, and know that Allah is All-Aware of everything.

(27) The mothers shall give suck to their children for two whole years, (that is) for those (parents) who desire to complete the term of suckling, but the father of the child shall bear the cost of the mother's food and clothing on a reasonable basis. No person shall have a burden laid on him greater than he can bear. No mother shall be treated unfairly on account of her child, nor father on account of his child. And on the (father's) heir is incumbent the like of that (which was incumbent on the father). If they both decide on weaning, by mutual consent, and after due consultation, there is no sin on them. And if you decide on a foster suckling-mother for your children, there is no sin on you, provided you pay (the mother) what you agreed (to give her) on reasonable basis. And fear Allah and know that Allah is All-Seer of what you do.

(28) There is no sin on you, if you divorce women while yet you have not touched (had sexual relation with) them, nor appointed unto them their Mahr (bridal-money given by the husband to his wife at the time of marriage). But bestow on them (a suitable gift), the rich according to his means, and the poor according to his means, a gift of reasonable amount is a duty on the doers of good.

(29) And if you divorce them before you have touched (had a sexual relation with) them, and you have appointed unto them the Mahr (bridal-money given by the husband to his wife at the time of marriage), then pay half of that (Mahr), unless they (the women) agree to forego it, or he (the husband), in whose hands is the marriage tie, agrees to forego and give her full appointed Mahr. And to forego and give (her the full Mahr) is nearer to At-Taqwa (piety, righteousness). And do not forget liberality between yourselves. Truly, Allah is All-Seer of what you do.

(30) And their Prophet (Samuel عليه السلام) said to them: Verily! The sign of His kingdom is that there shall come to you At-Tabut (a wooden box), wherein is Sakinah (peace and reassurance) from your Lord and a remnant of that which Musa (Moses) and Harun (Aaron) left behind, carried by the angels. Verily, in this is a sign for you if you are indeed believers.
