Hadith 1604

Malik said, "The generally agreed upon way of doing things amongus is that maternal half-siblings do not inherit anything when thereare children or grandchildren through sons, male or female. They donot inherit anything when there is a father or the father's father.They inherit in what is outside of that. If there is only one male orfemale, they are given a sixth. If there are two, each of them has asixth. If there are more than that, they share in a third which isdivided among them. The male does not have portion of two females.That is because Allah, the Blessed, the Exalted, says in His Book, 'Ifa man or woman has no direct heir, and he has a brother or sister, bythe mother, each of them has a sixth. If there are more than two, theyshare equally in a third.' " (Sura 4 ayat 12).
