How is the estate of a mother to be distributed, if she left behind five sons and two daughters, and she had a son who died before her and who had sons and daughters?

The division of the inheritance cannot be determined until the heirs are precisely identified. A son who dies before his mother does not inherit from her, and his children do not inherit from their grandmother if they are blocked by their uncles. If the deceased left only five sons and two daughters, the inheritance is divided among them by ta'sib (residuary inheritance), with the male receiving the share of two females. The inheritance would be twelve shares, with each son receiving two shares and each daughter receiving one share.
