It is prescribed, when death approaches any of you, if he leave any goods that he make a bequest to parents and next of kin, according to reasonable usage; this is due from the God-fearing. (2:180)

They ask thee for a legal decision. Say: God directs (thus) about those who leave no descendants or ascendants as heirs. If it is a man that dies, leaving a sister but no child, she shall have half the inheritance: If (such a deceased was) a woman, who left no child, Her brother takes her inheritance: If there are two sisters, they shall have two-thirds of the inheritance (between them): if there are brothers and sisters, (they share), the male having twice the share of the female. Thus doth God make clear to you (His law), lest ye err. And God hath knowledge of all things. (4:176)

And ye devour inheritance - all with greed, (89:19)
