“I once asked abu ‘Abd Allah (a.s.), about the case of a man who leaves behind his brother from his father and mother and his grandfather. He (the Imam) said, ‘The legacy between them is half and half. If they are two brothers or a hundred, the grandfather is with them like one of them. The grandfather with them receives a share like the share of one of the brothers.’ He (the Imam) said, ‘If he leaves behind a sister, then the shares of the grandfather are two shares and the sister receives one share, if the sisters were two, then one-half is for grandfather and one-half for the sisters.’ He (the Imam) said, ‘If he leaves behind brothers and sisters from his mother and father, the grandfather is like one of the brothers and each male receives twice as much as the share of a female.’”
