She died and left behind a husband, five sons and four daughters
Question

                The mother died, leaving behind a husband, five sons and four daughters. She owned some money, gold and land. How should the money, gold and land be divided? Is it permissible for us all to agree to give the money in charity as ongoing charity (sadaqah jaariyah) on behalf of our mother? Is it permissible for us males, including the father, to give up our share of the gold so that it will be part of the share of the females?.
Praise be to Allah.
    Firstly: 

    If a woman 
    dies and leaves behind a husband, five sons and four daughters, then the 
    estate is to be divided as follows:

    The husband 
    gets one quarter, because of the words of Allaah (interpretation of the 
    meaning): “In that which your wives 
    leave, your share is a half if they have no child; but if they leave a 
    child, you get a fourth of that which they leave” [al-Nisa’ 4:12].

    The children 
    get the rest, with each male getting the share of two females, because 
    Allaah says (interpretation of the meaning): “Allaah commands you as 
    regards your children’s (inheritance): to the male, a portion equal to that 
    of two females” [al-Nisa’ 
    4:11]. 

    When the 
    estate is shared out among the heirs, it should be divided into 56 equal 
    parts. The husband's share of it is 14 parts, the share of each son is six 
    parts and the share of each daughter is 3 parts. 

    So the 
    husband's share = the estate 
    
    × 14
    
    
    ÷ 56 

    The share of 
    each daughter = the estate 
    
    × 3
    
    
    ÷ 56 

    The share of 
    each son = the estate 
    
    × 6
    
    
    ÷ 56 

    Secondly: 

    The heir may 
    donate his share, such as making it a waqf (ongoing charity) on behalf of 
    his mother, so long as he is an adult of sound mind, because if the child or 
    foolish person who does not handle money well donates something, their 
    donation is not valid. 

    There is 
    nothing wrong with you donating part of the money or all of it to be ongoing 
    charity on behalf of your mother. This is part of respecting her and 
    treating her kindly. 

    Thirdly: 

    It is 
    permissible for the male heirs to give up their share of the gold to the 
    female heirs, if they are adults of sound mind as stated above. 

    If the father 
    gives up his share of the gold to the daughters, this comes under the 
    heading of giving gifts, and the basic principle is that the father should 
    be fair in giving to his children, and he should not favour the females over 
    the males. But if this is done with the consent of the males, there is 
    nothing wrong with it, and in that case they will be doing good and will be 
    rewarded, in sha Allaah. 

    May Allaah 
    help us all to do that which He loves and which pleases Him. 

    And Allaah knows best.
