The illuminated City, Madina, under the noble Prophet, peace be upon him, and then under those who immediately succeeded him, is the true dynamic model on which any Islamic society must be based. This model has for centuries been brought to life in different places and in many different times. These include the Mahgrib, Andalusia, West Africa, Topkapi and Nusantara.. At the heart of this model are the everyday contacts and contracts such as commercial transactions, money and of course Zakat. Muamalat is the thing that encompasses all of that and the Imaret is the place.
