Islam is the only nominated religion of Allah, which is complete code of life. A Muslim has to lead his/her life in the light of the code from the cradle to the grave. There are well-ordered social, political and economic systems in Islam. There are guidelines and principles for national and international interactions in Islam. There can be no alternative of Islam for the development of human character and in the formation and preservation of a progressive and well-ordered society based on the principles of equity and justice.
