The second is Zakat, charity. However pious and godly a person may be, however much time of his life he devoted to piety, he cannot deserve the blessing of God unless he is charitable, for charity is the only test of selflessness. All love and friendship is proved by service and sacrifice, and to the extent one is able to do it, one is selfless. And, self being the only barrier that stands between man and God, charity is the only means to break down that barrier, that man may be face to face with God.
