What is the ruling regarding a father who wants to distribute his inheritance to his children during his lifetime?

A father distributing his property among his children during his lifetime is considered a gift (hibah) and not a distribution of inheritance, and it is stipulated that justice must be observed among the children. Jurists have differed on how to achieve this justice: whether it should be like inheritance, with the male receiving the share of two females, or by equal distribution between males and females.
