Allah, the Almighty, has made sublime purposes for the legislation of the acts of worship. For example, regarding Prayer, Almighty Allah says:

And establish prayer. Indeed, prayer prohibits immorality and wrongdoing. (Al-`Ankabut 29:45)

Concerning fasting, Allah (Glory be to Him) says:

O you who have believed, decreed upon you is fasting as it was decreed upon those before you that you may become righteous. (Al-Baqarah 2:183)
