What is the share of each heir from the mentioned inheritance, given the presence of: a mother, one wife, seven sons, eleven full sisters, and twelve full brothers?

If the deceased left behind no heirs other than a mother, a wife, and seven sons, then the mother receives one-sixth due to the presence of a lineal descendant, and the wife receives one-eighth due to the presence of a lineal descendant. The remainder goes to the seven sons by ta'sib (agnatic inheritance). The brothers and sisters receive nothing, as they are excluded by the son. The estate is divided into 168 shares: the mother receives 28 shares, the wife receives 21 shares, and each son receives 17 shares.
