From speeches and advices of prophet Mohammed

One: From his advices to his trustee imam Ali bin Abi Talib

From the certainty is not to satisfy any person through disobeying God, not to praise any one for what God had given to you , not to dispraise any one for what God had deprived you whereas the livelihood doesn't come through greed and doesn't go by hatred

O Ali the ignorance is the worst poverty and no money best than mind and nor lonely worst than pride and nor noble as good ethic and nor worship as thinking

O Ali lie is the blight of speech , forgetting is the blight of science , languor is the blight of worship , oppression is the blight of bravery , vanity is the blight of beauty , pride is the blight of noble

O Ali three things are from the good ethic " the generosity , the good speech and to afford the harm

O Ali the one whom the people avoid him because of his bad speech will be in the hell

Two : He also said

One: The best one in faith is the best in ethic

Two: The mind is the friend of each person and the ignorance is his enemy

Three: Avoid the wine because it's the key for each evil

Four: The wrath of God is so sever on the adulterer

Five: cleanliness is from the faith
