their male and female are equal, except according to the analogy of the opinion of him who considers the cause (sabab) as null, for then the male receives the share of two females. What Al-Khiraqi reported is equality between all, except for the maternal uncle and the maternal aunt. I do not know of any who agree with him on this opinion, nor do I know its basis. As for his statement: "if their father is one and their mother is one," it is because the disagreement exists only regarding a male and a female whose father and mother are the same. As for when their fathers and mothers differ, such as the maternal uncles and maternal aunts who are of different categories (2), or the paternal aunts who are of different categories, or when each one of them derives their relation through a different person than the other, such as the son of a daughter and the daughter of another daughter, that is a different matter which shall be mentioned elsewhere, if God Almighty wills.

Among the issues of this is: the son of a sister with his sister, or the son of a daughter with his sister. The estate is divided between them in halves according to those who equalize them; and according to the scholars of proximity (ahl al-qaraba) and the rest of those who assign them to the status of legal heirs (munazzilin), the estate is divided between them into three.

And for the sister from the mother is one share, divided between her children into eight. The four is contained within it, and the six corresponds to it by half; so you multiply its half by eight, which becomes twenty-four, then by five, it becomes one hundred (6) and twenty. He who prefers [the male] leaves the children of the mother as they are, and makes the children of the sister from both parents six, their shares corresponding to them by a third, so they return to two, and they are contained within the eight. And the children of the sister from the father are nine; you multiply them by eight, which becomes seventy-two, then by five, which becomes three hundred and sixty. If they are the children of paternal aunts or maternal aunts of different categories, it is the same. And if they are the children of daughters, or children of...
