What is the ruling on the inheritance of a woman who died without children or a husband, and her heirs are: one full sister, and the sons and daughters of brothers, knowing that her parents and brothers (males) died before her? And do the daughters of brothers inherit in this case?

The children of a sister, both male and female, are not among the heirs. If a woman dies leaving behind one sister, the sister inherits all the wealth, regardless of whether she is a full sister, a paternal half-sister, or a maternal half-sister. As for the sons of brothers (but not sisters), whether full brothers or paternal half-brothers, they are among the heirs and receive the remainder by ta’sib (residuary inheritance) after the sister's share. If they are mixed, the sons of full brothers inherit, and the sons of paternal half-brothers are excluded. Inheritance matters are complex and should be brought before Sharia courts or experts in Islamic law should be consulted to ensure the rights of heirs and creditors.
