Musannaf Ibn Abi Shaybah

Ibrahim narrates regarding the woman who died leaving behind her maternal brother and sister, and also paternal cousins from among the 'asaba. He said that they will divide one-third of the wealth among themselves, in which the share of men and women will be equal, and the remaining two-thirds will be only for the men among them, not for the women. This is the decision of all the noble Companions. And according to the opinion of all the authorities, this issue will be resolved from three shares.
