If the son is poor and has a separate house, is it permissible for the father to give him from the zakah?

The questioner : If the son becomes independent and has a house of his own, or a son, and then disappears, is it permissible to give this son zakah? He became independent and had a wife and children, and then after a period of time he became poor. Is it permissible for his father to give him from the zakah, or is he only obligated to provide for them?

The Shaykh : Yes, it is not permissible to give it to him for maintenance, ever, because the father is obligated to provide for his son, even if he is in another house.

The questioner : And for the wife of my son.

The Shaykh : And for the wife of his son and for his sons and daughters.
