"[Charity is] for the poor who have been restricted for the cause of God, unable to move about in the land. An ignorant [person] would think them self- sufficient because of their restraint, but you will know them by their [characte- ristic] sign. They do not ask people per- sistently [or at all]. And whatever you spend of good - indeed, God is Know- ing of it."— Sahih Intl
