The systems of Islam, when implemented all together under a Khilafah State, form an integrated whole and create a unique society built solely upon the revelation of Allah (swt) and the example of His messenger, Muhammad (saw). This section will address the different systems of the Islamic State - Ruling, Economic, Social, Education and Judicial. Here, each system is considered, and is discussed on three different levels. First, are presented some key facts about the system, which are followed by a more detailed and holistic view of it. Finally, a particular issue which is of practical relevance to Muslims today will be focused upon, contrasting the ways in which these issues are dealt with under Islam on one hand, and in the Western world on the other. Indeed, today's world is characterised by a whole host of problems, that have come to be accepted as a fact of life. In this section, we will endeavour to show, Inshallah, how the deen of Islam provides comprehensive guidance for mankind in every area of life, and that the Islamic State is able to practically solve the everyday problems of people all around the world.
