How is the inheritance of a man distributed who died and left a wife, a full sister, and a maternal half-brother, and left no children or parents?

The male heirs are fifteen, and the female heirs are ten. If a person dies and leaves behind a wife, a full sister, and a maternal brother, and leaves no 'asaba (agnatic heir), then the wife receives one-quarter as a prescribed share, the full sister receives one-half as a prescribed share, and the maternal brother receives one-sixth as a prescribed share. In this case, there is a ردّ (return, or residual distribution) to the full sister and the maternal brother, but not to the wife. The estate will be divided as follows: it is divided into sixteen shares; the wife receives four shares, the full sister receives nine shares (as a prescribed share and by return), and the maternal brother receives three shares (as a prescribed share and by return). We emphasize the seriousness of matters related to inheritances and the necessity of referring them to Sharia courts or consulting knowledgeable scholars to verify all heirs, wills, debts, and rights.
