Note:
Kafala of Islamic law is a alternative means of child's care for children deprived of their family environment, for example, abandoned or orphaned children. Under Kafala, a family may take a child to live with them on a permanent, legal basis, but that child is not entitled to use of the family's name or to inherit from the family.
