When someone says, "My house is Sadaqa for Allah's sake,"

The Prophet (ﷺ) ﷺ allowed Abu Talha when he said, "The most beloved of my property is (the garden of) Bairuha and I wish to give it in charity for Allah’s sake." The Prophet (ﷺ) ﷺ considered his deed valid. Some say that it is invalid unless it is specified as to whom the Sadaqa is to be given. But the first statement (i.e., that it is valid) is more correct.
