It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that a man came to the presence of the Messenger of Allah (peace and blessings be upon him) and said, "Command me to do one thing, not many things, so that I may understand it well." The Holy Prophet (peace and blessings be upon him) said, "Do not get angry."
