The ruling on a father spending on his independent, poor son

The questioner : If the son has grown up and become independent of his father, having his own home, and has become poor, as we fear, and the father has zakah to pay out, does he pay it on his behalf, or do we say that it is obligatory for him to bear it?

The Shaykh : It is obligatory for him to spend on him if he is able. However, if the father has a family and is unable to spend on this son, he may give him from his zakah.

The questioner : Yes, if he has grown up and become independent of him.

The Shaykh : Even if he is independent, because it is not a condition for the obligation of spending that he not be independent. Yes.
