پیوند بهداشت و عبادات در قرآن و روایات

Abstract In Islam, cleanliness is accounted as the precondition of much worship. In many cases, it is considered as an act of worship and recommended ritual. This cleanliness can be investigated from the individual and social dimensions. Thus, we can discuss about the link between worship and individual/ social health. So that according to Quran and Tradition one of prophet's commissions was sanitation and cleanliness of clothes, body, food, and other aspects of human lives. This continues to the point that Islam accounts cleanliness as faith in a general rule. This issue is completely evident in relation with prayers, immersion, etc. The present study targets at investigating the link between individual /social cleanliness and worship.  It can be said that, these concepts of Quran mean both inward and outward health. For example, some verses indicate that healthy foods should be consumed or moreover, Muslims are asked not to pray when drunk and also to avoid eating murrain since it is accounted as unhealthy and unsanitary. In Islamic Traditions, great emphasis has been put on cleanliness and its relation to faith. For instance, the famous quotation of the holy prophet that says: "cleanliness (and hygiene) is part of faith." This indicates that human's faith is not complete without considering health issues.  Paying attention to different types of obligatory and recommended immersions as well as ablution shows the importance of cleanliness in Islam. Consequently, cleanliness is the main component of health and one can not be healthy without observing it. Therefore, a person cannot be pious while disregarding the principles of cleanliness.
