Sayyiduna Abu Ayyub (may Allah be pleased with him) reports that a man came to the Prophet Muhammad (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, and do not say anything for which you would have to apologize tomorrow, and be hopeless (and independent) of what people possess."
