Is it permissible for a man to distribute all his wealth to his heirs during his lifetime?

Answer

While it is permissible for a man to distribute all his wealth to his children, etc. during his life time, the intention should not be to deprive any particular heir without valid Shar'i reason. If he distributes his wealth during his lifetime, he should give equally to both sons and daughters. If he has a valid reason for preferring one child, hence giving him/her more, then it will be permissible, e.g. the one child cares more for the parents or he is the only one who works with them.
