Why isn't my Muslim client eating? Should I continue to work with my client while their caregiver prays? Do I have to change the way I teach toileting for my Muslim clients? With Islam being the second largest religion in the world and the third largest religion in America, these are questions that many service providers may find themselves asking. Service providers who will provide home-based or residential treatment to Muslim clients should be aware of common daily living practices, social expectations, dietary, and hygienic requirements of their clients who are practicing Muslims. Practicing Muslims pray 5 times a day, fast during the month of Ramadhan, may dress differently from other clients, and adhere to specific hygiene routines after using the bathroom. In order to provide ethical and culturally appropriate treatment, service providers should be aware of the practices of the practicing Muslim. In this paper the author will review basic guidelines for working with Muslim clients as well as review specific intake questions that service providers should consider asking when working with Muslim clients.
