We are given suggestions on how to engage in simple thing such as eating, visiting friends, personal hygiene, dressing and studying to name a few. Because so much of what we learn in medical school revolves around the health status of an individual and little emphasis is placed on community health, I will keep this discussion focused on the health of the individual covered by the Hold Quran. We wash our hands, mouth, nose, face, arms to the elbows, wipe water over our hair, our ears and our feet to our ankles.
Physical impurities are such things as urine, or blood or puss.
Cleanliness in general is a MUST for all Muslims. I have one memory of my grandfather. I remember he used to eat wood. I was 3, and very confused. The Miswak is actually similar to a twig.
