Philosophers talked about high moral values and said that they are: Truth, goodness and beauty, but those manners they mentioned differ from one person to another.
High manners are those got by religions, as they were set and recommended by God who knows the good for His creatures. The high manners got by Islam are those that if they are fulfilled at any age or any place, surly this age and this place will be happy. They are freedom, fair, equality, truthfulness, magnanimity and honesty. For example, God set in Koran the principle of goodness and reforming societies in two of those moral values, He says:
“Allah does command you to render back your Trusts to those to whom they are due; and when you judge between man and man, that you judge with justice:” Surat An’nesaa, Verse 58.
