The eleventh chapter of The Revival of the Religious Sciences begins the section dealing with man & society. In this volume concentrating on the manners relating to eating Ghazali first discusses what a person must uphold when eating by himself: that the food is lawful that both the person & the surroundings should be clean that one must be content with what is available & how the person should conduct himself while eating & after eating. Ghazali then proceeds to discuss eating in company & says that to all the above should be added the necessity of courtesy conversation & the proper presentation of food. Finally Ghazali expounds the virtues of hospitality & generosity & the conduct of the host as well as that of the guest. Other topics that are discussed are: abstention from food fasting & general health.
