Answer
(Fatwa: 511/H=181/th=1432)
Your grandmother is now alive; whatever is in her possession its division is not wajib on her. However, all the property and other things that were in the possession of the deceased grandfather (nana) became his inheritance and it is wajib to divide it as soon as possible. The method of it is that after paying of the due rights preceding inheritance and provided the details of the heirs are correct, all the property of the deceased grandfather shall be divided into 136 shares. The widow of the deceased shall get 17 shares, each son 14-14 shares and each daughter 7-7 shares, as per the following detail:
Detail:
Wife: 1×17 = 17
Son: 7×14 = 98
Daughter: 3×7 = 21
Total: 136 Shares
Note: The property of the deceased grandfather should be divided according to what we have written. If the grandmother and maternal uncle did not have any wrong intention and they did some mistake due to lack of correct knowledge, which they shall make up now, then in-sha-Allah they shall not be deprived of the acceptance of Hajj.
