The manner of friendliness is considered as the main part in the study of Sufism, for the Sufi in all ages has given great importance to the art of personality. As Sufism is the religious philosophy of love, harmony and beauty, it is most necessary for a Sufi to express the same through his personality. No doubt in the East, manner is given great prominence in life. The courts in the East were schools of good manners, though a great deal of artificiality was combined with it, but in the path of Sufism the same manners which are used at court were learned with sincerity.

According to the Sufi idea all beauty comes from God, so a beautiful manner is a divine expression.

In these modern times people seem to be against manners because of their agitation against aristocracy, as there are many who are against religion because they are cross with the priests. When man agitates against beauty he cannot be on the right path, and the movement of today against all beauty that exists in the form of culture and manner is a battle with civilization.

The Sufi calls the manner that comes from the knowledge of unity, from the realization of truth, from the love of God, Akhlaq Allah, meaning the "Manner of God." In other words, God expressed in man shows in the action of that man the manner of God.
