and a grandfather, the estate is divided among them into five; the grandfather receives two shares, and the remainder is for the brother. According to both [Abu Hanifa and Muhammad ibn al-Hasan], the estate is divided between them into two halves.

Section: Two brothers of two parents, a brother from a father, and a grandfather; the grandfather receives the third, and the remainder is for the two brothers of two parents according to everyone. If the children of the two parents are three, the grandfather also receives the third according to Zayd. According to Ali and Ibn Mas'ud, he receives the fourth; because they divide the estate with him down to the sixth. A brother and a sister from two parents and a brother from a father or more than that; the grandfather receives the third, and according to both [Abu Hanifa and Muhammad], the grandfather receives two-fifths, the brother of two parents receives two-fifths, and the sister receives one-fifth.

1024 - Issue; he said: "If there is a brother and a sister from a father and mother, or from a father, and a grandfather, the estate is between the grandfather, the brother, and the sister on five shares; for the grandfather two shares, for the brother two shares, and for the sister one share."

Division (muqasama) here is better for the grandfather than the third; because he obtains two-fifths of the estate through it, and that is better for him than the third. Likewise, whenever the brothers are fewer than two, or those who equal them from among the females, such as three sisters, or two sisters, or one brother, or one sister, there is nothing for him but division with them like a brother. This is the view of Zayd, Ali, and 'Abd Allah when they are agnates ('asaba). However, if they are female siblings alone, then Ali and Ibn Mas'ud assign them their fixed shares (fara'id), then give the grandfather what remains.

1025 - Issue; he said: "And if there is a sister from a father and mother, a sister from a father, and a grandfather, the obligatory share [between the grandfather] and the two sisters is on four shares; for the grandfather two shares, and for each sister one share, then the sister from the mother and father returns and takes from what is in her sister's hand to complete the half."

Division here is more advantageous for the grandfather, and the sister of two parents counts her sister from the father against the grandfather.
