He died and left behind a wife, two sons and three daughters
If the father dies and leaves behind a wife, two sons and three daughters, then the wife gets one-eighth, because Allaah says (interpretation of the meaning):
“if you leave a child, they [wives] get an eighth of that which you leave”
The rest goes to the children (males and females), 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”
Based on that:
The wife’s share is 2500 dinars.
The share of each male is 5000 dinars.
The share of each female is 2500 dinars.
And Allaah knows best.
