Allah commands you concerning your children, the share of male is equal to the share of two females; then if there be daughters only, though more than two, then for them is two third of what is left, and if there be only one daughter, for her is one half. And for each of the parents of the deceased is one sixth of what is left, if there be a child of the deceased, but if he has no child and leaves parents, then for the mother is one third; but if there be his many sisters and brothers, then for the mother is one sixth, after any bequest which has been made and debts. Your fathers and your sons, you know not which of them will be more profitable to you. This is fixed proportion from Allah. Undoubtedly Allah is All Knowing, Wise.
