What is the ruling in the case known as 'Al-Kharqi' involving a full sister, a paternal sister, and the grandfather?
Chapter on Inheritance of the Grandfather
Al-Mughni
Book of Inheritance Shares (Farā'id)
Primary text
Ali and Abdullah assign half to the full sister, one-sixth to the paternal sister, and the remainder to the grandfather. This applies even if there are two or more paternal sisters.

When the division is based on six shares (two for the grandfather, two for the full brother, one for each sister), the paternal sister claims from the others to complete half. The distribution is then corrected to eighteen shares: six for the grandfather, nine for the full sister (from both parents), two for the brother, and one for the paternal sister. Participatory division (Muqasama) and receiving one-third are equal here. If participatory division is used, the total becomes eighteen shares as stated by Al-Kharqi. If the paternal relatives exceed this number, they receive no more than one-sixth because the grandfather cannot receive less than one-third, and the sister cannot receive less than half.
