It is narrated from Masruq (may Allah have mercy on him) that: Sayyida Aisha (may Allah be pleased with her) used to include two daughters and a granddaughter and a grandson in inheritance. Thus, she would give the two daughters two-thirds, and the remaining one-third she would distribute among all of them.
And Sayyiduna Abdullah ibn Mas'ud (may Allah be pleased with him) did not include the granddaughter; whatever remained, he would distribute only among the males, and he used to say: Sisters are in the position of daughters.

Brief Explanation
(Commentary on Hadiths 2924 to 2927)
This issue, according to the opinion of Umm al-Mu’minin Sayyidah A’ishah radi Allahu anha, is as follows: If a man passes away and leaves behind two daughters, a grandson, and a granddaughter, then the two daughters will receive two-thirds, and from the remaining one-third, under the rule of “for the male, a portion equal to that of two females” (lil-dhakari mithlu hazz al-unthayayn), the grandson will receive two shares and the granddaughter one share.
And the issue will be calculated out of 9.
Two daughters . . . . two-thirds . . . . 6 One grandson . . . . two shares . . . . 2 One granddaughter . . . . one share . . . . 1
Sayyiduna Ali and Sayyiduna Zayd ibn Thabit radi Allahu anhuma also held this same view.
However, according to Sayyiduna Ibn Mas’ud radi Allahu anhu, whatever remains after the daughters’ share will all go to the grandson, and the granddaughter will be deprived.
