In the name of Allah, the Most Gracious, the Most Merciful

(2:180) Prescribed for you when death approaches [any] one of you if he leaves wealth [is that he should make] a bequest for the parents and near relatives according to what is acceptable – a duty upon the righteous.
(2:181) Then whoever alters the bequest after he has heard it – the sin is only upon those who have altered it. Indeed, Allah is Hearing and Knowing.
(2:182) But if one fears from the bequeather [some] error or sin and corrects that which is between them, there is no sin upon him. Indeed, Allah is Forgiving and Merciful.

(2:188) And do not consume one another’s wealth unjustly or send it [in bribery] to the rulers in order that [they might aid] you [to] consume a portion of the wealth of the people in sin, while you know [it is unlawful].

(4:7) For men is a share of what the parents and close relatives leave, and for women is a share of what the parents and close relatives leave, be it little or much – an obligatory share.
(4:8) And when [other] relatives and orphans and the needy are present at the [time of] division, then provide for them [something] out of the estate and speak to them words of appropriate kindness.
(4:9) And let those [executors and guardians] fear [injustice] as if they [themselves] had left weak offspring behind and feared for them. So let them fear Allah and speak words of appropriate justice.
(4:10) Indeed, those who devour the property of orphans unjustly are only consuming into their bellies fire. And they will be burned in a Blaze.
(4:11) Allah instructs you concerning your children: for the male, what is equal to the share of two females. But if there are [only] daughters, two or more, for them is two thirds of one’s estate. And if there is only one, for her is half. And for one’s parents, to each one of them is a sixth of his estate if he left children. But if he had no children and the parents [alone] inherit from him, then for his mother is one third. And if he had brothers [or sisters], for his mother is a sixth, after any bequest he [may have] made or debt. Your parents or your children – you know not which of them are nearest to you in benefit. [These shares are] an obligation [imposed] by Allah . Indeed, Allah is ever Knowing and Wise.
(4:12) And for you is half of what your wives leave if they have no child. But if they have a child, for you is one fourth of what they leave, after any bequest they [may have] made or debt. And for the wives is one fourth if you leave no child. But if you leave a child, then for them is an eighth of what you leave, after any bequest you [may have] made or debt. And if a man or woman leaves neither ascendants nor descendants but has a brother or a sister, then for each one of them is a sixth. But if they are more than two, they share a third, after any bequest which was made or debt, as long as there is no detriment [caused]. [This is] an ordinance from Allah, and Allah is Knowing and Forbearing.
(4:13) These are the limits [set by] Allah, and whoever obeys Allah and His Messenger will be admitted by Him to gardens [in Paradise] under which rivers flow, abiding eternally therein; and that is the great attainment.
(4:14) And whoever disobeys Allah and His Messenger and transgresses His limits – He will put him into the Fire to abide eternally therein, and he will have a humiliating punishment.

(4:33) And for all, We have made heirs to what is left by parents and relatives. And to those whom your oaths have bound [to you] – give them their share. Indeed Allah is ever, over all things, a Witness.
(4:34) Men are in charge of women by [right of] what Allah has given one over the other and what they spend [for maintenance] from their wealth. So righteous women are devoutly obedient, guarding in [the husband’s] absence what Allah would have them guard. But those [wives] from whom you fear their ill-conduct – advise them; forsake them in bed; and separate them. But if they obey you [once more], seek no means against them. Indeed, Allah is ever Exalted and Grand.
(4:35) And if you fear dissension between the two, send an arbitrator from his people and an arbitrator from her people. If they both desire reconciliation, Allah will cause it between them. Indeed, Allah is ever Knowing and Acquainted [with all things].

(4:176) They ask you for a legal decision, Say: Allah gives you His decision about those who leave no descendants or ascendants as heirs.  If a man dies childless and leaves behind a sister, she shall inherit one-half of his estate.  If a woman dies childless, her brother will inherit all of her estate.  If the childless person leaves behind two sisters, they both shall inherit two-third of his estate; but if he leaves more than two brothers and sisters, the share of each male shall be equal to that of two females.  Thus Allah makes His commandments clear to you lest you go astray.  Allah has perfect knowledge of everything.

(5:105) O you who have believed, you are accountable for none but for yourselves; anyone who has gone astray cannot harm you if you are on the Right Way. To Allah you shall all return and He will let you know the truth of all that you did.
(5:106) O you who have believed, testimony [should be taken] among you when death approaches one of you at the time of bequest – [that of] two just men from among you or two others from outside if you are traveling through the land and the disaster of death should strike you. Detain them after the prayer and let them both swear by Allah if you doubt [their testimony, saying], “We will not exchange our oath for a price, even if he should be a near relative, and we will not withhold the testimony of Allah . Indeed, we would then be of the sinful.”
(5:107) But if it is found that those two were guilty of perjury, let two others stand in their place [who are] foremost [in claim] from those who have a lawful right. And let them swear by Allah, “Our testimony is truer than their testimony, and we have not transgressed. Indeed, we would then be of the wrongdoers.”
(5:108) That is more likely that they will give testimony according to its [true] objective, or [at least] they would fear that [other] oaths might be taken after their oaths. And fear Allah and listen; and Allah does not guide the defiantly disobedient people.
