Abstract
Maintaining the family is the basis for maintaining the Muslim society because the family is the first unit of the society. To keep the family strong and cohesive, it needs a law, and this law is embedded in the Sharia. We will deal in this thesis with the justice that we are ins- tructed to obey by the Sharia inside the Muslim family, whether it is about the justice amongst wives or children, providing evidence from the sharia for each of them.
