Abu Ayyub Ansari (may Allah be pleased with him) narrates that a man came to the Noble Prophet (peace and blessings be upon him) and said, "Give me some concise and comprehensive advice." The Prophet (peace and blessings be upon him) said: "When you perform prayer, perform it as if it is your last prayer (of your life), and do not say anything for which you would have to apologize tomorrow, and be completely hopeless (and independent) of what people possess."
