He died and left behind a wife, sons and daughters, and some of his children died before him. Do his grandchildren inherit the shares of his children who died before him?
Question

                My father died and left us a house, and we want to sell the house. How should we share out (the price)? We are six males and two females, in addition to our father’s wife. Please note that two of my brothers died (before our father), and they left wives and children, both male and female.
Praise be to Allah.
      Those who are 
      entitled to a share of the estate, which comprises the price of the house 
      after it is sold, are the wife and children of the deceased. 

    As for the wife, 
    she gets one eighth, because there are descendants who inherit. Allah, may 
    He be exalted, says (interpretation of the meaning): “their 
    (your wives) share is a fourth if you leave no child; but if you leave a 
    child, they get an eighth of that which you leave” 
    [an-Nisa’ 4:12]. 

    The remainder of 
    the estate goes to the children, with each male getting the share of two 
    females, i.e., each male gets double what each female gets, because Allah, 
    may He be exalted, says (interpretation of the meaning): 
    “Allah commands you 
    as regards your children’s (inheritance); to the male, a portion equal to 
    that of two females” [an-Nisa’ 4:11]. 

    With regard to your 
    brothers who died whilst their father was still alive, their children and 
    wives are not entitled to any share of the estate, because one of the 
    conditions of inheritance is that the heir should still be alive after the 
    death of the testator, and this condition is not applicable to your two 
    brothers who died whilst your father was still alive. Therefore they are not 
    entitled to a share of the estate, and their children are not entitled to a 
    share of the estate either, because they are blocked from inheriting by 
    their paternal uncles. 

    Shaykh ‘Abdullah 
    ibn Jibreen (may Allah have mercy on him) was asked: Do grandchildren 
    inherit from their grandfather if their father died before their 
    grandfather? If the answer is no, then why? 

    He replied: 
    Grandchildren [for the purpose of inheritance] are the children of sons, not 
    the children of daughters. If their father died before his father, they do 
    not inherit from the grandfather if he had another son or sons, because a 
    son is closer than a son’s son. If the grandfather did not have any sons, 
    not even one, and he only had daughters, then the grandchildren inherit what 
    remains after the daughters are given their share of inheritance. Similarly, 
    they inherit from their grandfather if he did not have any sons or 
    daughters; in that case they take the place of his children, with each male 
    getting the share of two females.

    But it is 
    recommended for you and your siblings not to deprive your brothers’ children 
    of anything of the estate, so as to make them feel better, and so that the 
    pain of their father’s death will not be compounded by being deprived of 
    wealth. Allah, may He be exalted, says (interpretation of the meaning):
    “And 
    when the relatives and the orphans and Al-Masaakeen (the poor) are present 
    at the time of division, give them out of the property, and speak to them 
    words of kindness and justice” 
    [an-Nisa’ 4:8]. 
    So agree amongst yourselves to give them something in a way that will 
    benefit them and not harm you, uphold your ties of kinship with them and 
    make them feel better. 

    Al-Qurtubi (may 
    Allah have mercy on him) said: Here Allah, may He be exalted, explains that 
    those who are not entitled to any share of the inheritance but are present 
    when the estate is divided, and they are relatives or orphans or poor people 
    who do not inherit, should be honoured and should not be deprived, if the 
    wealth is plentiful, and apologies should be given to them if it is real 
    estate or is too little and cannot be divided. Even if what is given is 
    small, it will bring a great reward; one dirham given in charity may bring a 
    greater reward than one hundred thousand. End quote. 

    And Allah knows 
    best.
