Besides many other reasons which are responsible for the spread of Islam, it is the exemplary life-style and unceasing efforts of individual Muslims to transmit the message of Islam throughout the world which lies at the root of the conquest of the hearts by Islam. Islamic universalism is closely associated with the principle of Amr bi`l-ma`ruf (enjoining the good) for Islam is to be spread by Muslims by means of Amr bi`l-ma`ruf. This principle seeks to convey the message of Islam to all human beings in the world and to establish a well modeled Islamic community on a world-wide basis. The Islamic community is introduced by the Quran as a model community: "Thus, We have made of you an Ummah justly balanced, that you might be witnesses (models) for the peoples, and the Messenger has been a witness for you." (The Quran, 2:143) Thus, a Muslim or the Muslim community as a whole has a goal to achieve: This is the spread of Islam, conveying the truth to the remotest corners of the world, the eradication of oppression and tyranny and the establishment of justice all over the world. This requires Muslims to live an exemplary life, and thus the moral and ethical values of Islam have usually played an important part in the spread of Islam.
