Sayyiduna Abu Umamah (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) saying: "If you spend your surplus, it is better for you, and if you withhold it, it is bad for you. There is no blame for (keeping) what is sufficient. Begin with those you support, and the upper hand is better than the lower hand."
