What is the share of the sole niece from inheritance when there are five male cousins from the third grandfather?

The niece (daughter of the brother) is not among the inheritors; rather, she is from the kin (dhawu al-arham). However, the sons of the paternal great-grandfather's third paternal uncle are 'asabah (agnatic heirs), and they inherit the estate by ta'sib (agnatic succession) equally if there are no closer 'asabah. Inheritance matters should be brought before Sharia courts or discussed orally with scholars to ensure a comprehensive determination of heirs, debts, bequests, and other rights.
