Is it permissible to place an interdiction on a 92-year-old father who has disposed of his private wealth through gifts to some of his children but not others, and has refused to communicate with his son who seeks to speak with him?

A father must be equitable among his children in gift-giving, such that he gives the male twice the share of the female, in accordance with the Prophet's (peace and blessings be upon him) saying: "Fear Allah, and be just among your children." It is legislated to place an interdiction upon a profligate father who squanders and wastes money, but this interdiction is only effective by a judge's ruling. However, mere lack of justice among children does not mean that the father is profligate, warranting an interdiction upon him.
