What about food?

Although much simpler than the dietary law followed by Jews and the early Christians, the code which Muslims observe forbids the consumption of pig meat or any kind of intoxicating drink. The Prophet taught that 'your body has rights over you', and the consumption of wholesome food and the leading of a healthy lifestyle are seen as religious obligations.
The Prophet said: 'Ask God for certainty [of faith] and well-being; for after certainty, no one is given any gift better than health!'
