How is the inheritance divided between a mother, a wife, three sons, a daughter, a grandson, a sister, three paternal half-brothers, two maternal half-sisters, seven paternal nephews, and a granddaughter, knowing that the deceased's mother waived her share in favor of the deceased's children in exchange for them not claiming her inheritance after her death?

The mother gets one-sixth and the wife one-eighth due to the presence of a direct descendant. The remainder goes to the sons and daughters by ta'sib (residuary inheritance), with the male receiving the share of two females. Nothing goes to the remaining heirs because they are excluded by the son. The mother's waiver of her share to her grandsons on the condition that they do not inherit from her is void, as they do not inherit from her originally, and the condition negates a legitimate right. Inheritance matters must be referred to the Sharia courts to verify the existence of heirs, wills, or debts.
