Jahm bin Dinar narrated from Ibrahim (may Allah have mercy on him) that it is reported from him: He was asked: There are two sisters, one of whom bought her father and set him free, then he (the father) passed away. So Ibrahim (may Allah have mercy on him) said: Both sisters will receive two-thirds as the share prescribed in the Holy Qur'an: «فَلَهُمَاالثُّلُثَانِمِمَّاتَرَكَ . . . . . .»[النساء: 176/4] Whatever remains will be only for the daughter who set him free. That is, the other sister will not receive anything from the remaining share beyond the two-thirds, and the entire remainder will go to the emancipating daughter.
