It is narrated from Hazrat Abu Dharr (may Allah be pleased with him) that once the Noble Prophet (peace and blessings be upon him) said to him: "There are six days, after that, O Abu Dharr! Whatever I say to you, understand it well." When the seventh day came, the Noble Prophet (peace and blessings be upon him) said: "I advise you, both in secret and in open, to fear Allah. Whenever you commit a sin, then after it, do a good deed. Do not ask anything from anyone, even if your whip falls down (do not ask anyone to pick it up for you). Do not take possession of a trust, and never judge between two people."
