Sayyiduna Haritha bin Wahb (may Allah be pleased with him) said that I heard the Noble Prophet (peace and blessings of Allah be upon him) say: "Give charity, for a time will come upon you when a person will go out with his wealth to give in charity, but he will not find anyone to accept it. (Whoever he goes to with the charity) will reply: 'If you had brought it yesterday, I would have accepted it, but today I have no need of it.'"
