What is the share of each heir from the estate of a man who passed away, leaving behind a wife, one daughter, and the sons of a full brother (one son and three daughters), and the children of two full sisters (one son from the first, and one son and two daughters from the second)?

Half of the inheritance is given to the daughter and one-eighth to the wife, based on the Almighty's saying: "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 what he left. And if there is only one, she will have half." And the Almighty's saying: "But for them [wives], you have a fourth of what you leave if you have no child. But if you have a child, for them is an eighth of what you leave, after any bequest you [may have] made or debt." Whatever remains is given to the brother's son, and nothing to the brother's daughters or the sisters' children, because the Prophet (peace be upon him) said: "Give the prescribed shares to those who are entitled to them, and whatever remains is for the nearest male relative." The matter of inheritances must be submitted to the Sharia courts for investigation regarding the existence of wills, debts, or rights that take precedence over the heirs' rights.
