Physical Purity Physical Purity means cleanliness of the body, clothing and the enviroment. According to the rules of Islam, Muslims should keep their bodies and clothing clean from any impurity.
Impurity is excretion from anything human or animalistic.
It is a must for humans to wipe off the last drops of urine from their bodies with tissue paper and to not allow specks of dried feces to cling to any parts of their bodies, even on clothing. After wiping with tissue paper, Muslims should find water and wash away thoroughly all the impurities on them. Also applying to this rule are semen discharges and ejaculations. Muslims should wash away any and all discharges received from animals during play, etc. This includes the saliva from dogs on the human body, clothing, or on dishes used by humans for food.
