Who is the legal guardian over the funds of a minor and the incapacitated?

The one with the most right to guardianship over a minor or someone in their similar position is the father, then the grandfather. If neither exists, then it is the father's appointed guardian. If the latter does not exist, then it is the judge of the child's town. If the judge is not available, then guardianship belongs to righteous Muslims. The mother and relatives have no guardianship unless by appointment. If the incapacitation is due to insanity or foolishness, the ruling is as previously stated. However, if the incapacitation does not affect one's intellect, then they are considered mature and can manage their wealth as they wish, provided they are adult and of sound mind. If they are a minor, the ruling is as previously mentioned.
