Malik said, “The generally agreed on way of doing things among us is that full siblings do not inherit anything with sons nor anything with grandsons through a son, nor anything with the father. They do inherit with the daughters and the granddaughters through a son when the deceased does not leave a paternal grandfather. Any property that is left over, they are in it as paternal relations. One begins with the people who are allotted fixed shares. They are given their shares. If there is anything left over after that, it belongs to the full siblings. They divide it between themselves according to the Book of Allah, whether they are male or female. The male has a portion of two females. If there is nothing left over, they have nothing.
“If the deceased does not leave a father or a paternal grandfather or children or male or female grandchildren through a son, a single full sister gets a half. If there are two or more full sisters, they get two thirds. If there is a brother with them, sisters, whether one or more, do not have a fixed share. One begins with whoever shares in the fixed shares. They are given their shares. Whatever remains after that goes to the full siblings. The male has the portion of two females except in one case, in which the full siblings have nothing. They share in this case the third of the half-siblings by the mother. That case is when a woman dies and leaves a husband, a mother, half-siblings by her mother, and full siblings. The husband has a half. The mother has one sixth. The half-siblings by the mother have a third. Nothing is left after that, so the full siblings share in this case with the half-siblings by the mother in their third. The male has the portion of two females in as much as all of them are siblings of the deceased by the mother. They inherit by the mother. That is because Allah, the Blessed, the Exalted, said in His Book, ‘If a man or a woman has no direct heir and he has a brother or a sister, each one of the two gets a sixth. If there are more than that, they share equally in the third.’ (Sura 4 ayat 12). They therefore share in this case because all of them are siblings of the deceased by the mother.”
