An-Nisa · 4:11

11. Allah instructs you in the matter of the inheritance of children that the inheritance should be divided between them. A son gets a share equal to the share of two daughters. If the person who died left daughters without a son, two daughters or more get two thirds of what is left. If there is just one daughter, she gets a half of what is left. For each of the parents of the person who has died, they get a sixth of what is left, if he has children. If he does not have children or any heir except for his parents, then the mother gets a third, and the father gets the rest. If the person who has died has two or more siblings, whether brothers, sisters, half-brothers, or half-sisters, then his mother gets a sixth as a share, and the father gets the rest – so the brothers and sisters are not given anything. This division of the inheritance is after the bequests of the will have been deducted, with the condition that the bequests in the will cannot be more than a third of the total wealth and debts have been repaid from the wealth. Allah has made the division of inheritance like this because you do not know whether your parents or your children are closer to you in benefit in this world and the next. For instance, a person may think well of someone and leave everything to them, or think badly of someone and not leave them anything, and they may be wrong in their opinion in both cases. Allah knows the reality of things and nothing is hidden from Him. For this reason, the division of inheritance is as He made clear, and He made it obligatory for His servants. Allah knows everything, and nothing is hidden from Him of what is good for His servants – He is Wise in His sacred law and administration.
