If believe if each individual muslim tries to be a better believer, continuously trying to improve themselves, striving to perfect our charactor and imaan then i believe the entire market place will be under the influence of this ummat and the banner of Islam will rise once again. There is real power and benefit in this deen, however the fruits are only yielded when the deen is practised, applied in our way of life, otherwise 'market place' will dominate us. Islam is not a person, its a way of life, when implemented then it will bring peace/unity.
