Without dwelling on historical details, we can observe that Muhammad performed his role as administrator of Medina masterfully: in his younger life he had established himself as a businessman, and now he found himself ruling a city.
Here he is again distinguished from the founders of Christianity and Buddhism by the integration of social life, legal administration, and economic policy into his career as Prophet. This integration is in fact a characteristic of Islam that makes it difficult for the West to grasp, since today human life is divided into ‘spheres’ and religion is to keep out of sight or at least to be pursued in private under the rule of ‘separation of Church and State’. This has never been and could not ever be possible for Islam, and it is appropriate that the Prophet demonstrated the all-encompassing nature of Islam through his own activities. He did not disdain politics but established a just political order; he did not disdain economics and trade but established a just economic policy; he did not disdain marriage but establish rules that reinforced it; and so on.
