Shu'bi (may Allah have mercy on him) said: Sayyiduna Ibn Mas'ud (may Allah be pleased with him) used to say regarding a daughter, several granddaughters, and a grandson, that if their share in the division was less than one-sixth, he would still give them one-sixth, and if it was more than one-sixth, he would still give them one-sixth.
Daughter: half 3
Grandson: two shares
Granddaughter: share of one-sixth
