How is the inheritance divided among three sons, one daughter, and two grandsons (sons of a son)?

If the deceased's heirs are only his direct sons and daughter, then the grandsons do not inherit due to the presence of the sons. The inheritance is divided into seven shares: two shares for the male and one share for the female, based on the Almighty's saying: "Allah instructs you concerning your children: for the male, what is equal to the share of two females." It is recommended to give the grandsons something from the inheritance during the division, based on the Almighty's saying: "And when [other] relatives and orphans and the needy are present at the time of division, then provide for them [something] out of it and speak to them words of kindness." Inheritance matters must be referred to the Sharia courts for investigation and to ensure that there is no other heir, or any wills or debts that take precedence over the rights of the heirs.
