Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) says: I heard the Messenger of Allah (peace and blessings be upon him) while he (peace and blessings be upon him) was delivering a sermon: "The upper hand is better than the lower hand; the upper hand is the one that spends, and the lower hand is the one that asks."
