A Muslim tries to maintain the ritual purity of his body,
clothes and everyday commodities by avoiding contact with impure things because
such contacts would render the other items impure and would, therefore
necessitate the process of purification.
Residing in a non-Muslim country makes the process of maintaining purity difficult for some Muslims as they deal with its non-Muslim citizens in various situations of their day-to-day life: in restaurants, cafes, barber's shops, laundrettes, and, in public baths and utilities, etc. Therefore, it is appropriate for me to clarify for the respected readers the religious rules concerning taharat (ritual purity) and najasat (ritual impurity).
