How does a father justly distribute gifts among his male and female children, and how should a father treat his son who works with him?

Justice must be observed among children in giving gifts, and this is done by giving the male double the female's share in pure donations, similar to inheritance. As for maintenance, justice is achieved by giving each child what they need. If one of the children works with his father, he must be treated as a stranger and given a wage or a percentage of the profits in return for his work.
