Islam is a practical not a theoretical religion. Before a Muslim asks the society to reform itself, he has to apply the Islamic rulings in his own life. Islam empowers the value of self-improvement. God says in the Holy Quran: " Lo! Allah changeth not the condition of a folk until they (first) change that which is in their hearts." (13:11). So a Muslim should always be trying to make himself better.
Our Noble Prophet, peace and blessings be upon him said: “I have only been sent to complete upright moral character.” (Musnad Ahmad 2/381). He also said:"There is nothing which is heavier upon the Balance than good character." [Reported by Ahmad and Aboo Daawood).
Islam believes in our power to change ourselves, if Islam is not reflected on our behavior towards others regardless of their race, religion or sex or any other point of discrimination, then we are not true Muslims. Islam is NOT wearing galabia and having a beard, unfortunately this is how the ignorant, even among Muslims themselves, sees Islam. A Muslim is bound to apply the rulings of Islam on himself first before asking others to apply it.
Consequently, if a Muslim claims to be superior or is dealing with people in an unacceptable manner then he is not a good Muslim and knows nothing about the REAL Islam.
Islam believes in self-reformation and that IS NOT by denying yourself lawful worldly pleasures but rather by having an awaken conscience when dealing with everything and everyone. God says: " Say: Who hath forbidden the adornment of Allah which He hath brought forth for His bondmen, and the good things of His providing?" (7:32)
