4:6Test the orphans until they reach the age of marriage. If you find them to be mature enough, hand over their properties to them. And do not consume it extravagantly or hastily before they grow up. The rich shall not charge any wage, but the poor may charge fairly. When you hand over their properties to them, have it witnessed for them. God suffices as a Reckoner.
