He died and left behind a wife, his parents, a son and daughter
Question

                He died and he had a wife, a son and a daughter, and a mother and a father.

How should the house and car that are inherited be divided?.
Praise be to Allah.If a man dies and 
    leaves behind a wife, a son and a daughter, and a mother and a father, the 
    estate is to be divided as follows: 
The wife gets one 
    eighth, because Allah says (interpretation of the meaning): 
    “but if you leave a child, they [wives] get an eighth of that 
    which you leave”
[al-Nisa’ 
    4:12]. 
The father gets 
    one sixth and the mother gets one sixth, because Allah says (interpretation 
    of the meaning):
“For parents, 
    a sixth share of inheritance to each if the deceased left children”
[an-Nisa’ 
    4:11]. 
The rest goes to 
    the son and daughter, with the male getting a share equal to that of two 
    females, because Allah 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]. 
To divide the 
    estate among the heirs, it must be divided into twenty-four equal shares of 
    which
the mother gets 
    four
the father gets 
    four
the wife gets 
    three.
The remaining 
    thirteen shares go to the son and daughter, with the son getting double what 
    the daughter gets. 
The heirs can 
    agree to sell the house and car and divide the money amongst themselves, or 
    they can keep them to rent out and share the income amongst themselves. 
And Allah knows best.
