Answer
(Fatwa: 147/110/H=1434)
After paying due rights preceding inheritance and provided the details of the heirs are true, all the property of non-married deceased sister shall be divided into 40 shares out of which 18 shares shall go to the brother, and 9-9 shares to each sister and 4 shares to the daughter of deceased sister. And if the husband of the deceased sister is alive then the ruling shall be different in this case. If it is so then submit the question again. The detail of division is as follows:
Details:
Brother: 1×18 = 18
Sisters: 2×09 = 18
Niece: 1×04 = 04
Total: 40
