Cleanliness is of utmost importance in performing ibadah in Islam. According to the fiqh of Imam al Shafi’i, there are two kinds of impurity that needs to be clean from, namely al-najasat and al-hadath.
The definition of najasat ( filth?) is anything dirty which prevents the validity of salat.
The category of najasat as outlined by the book al-Fiqh al-Manhaji is as follows:
- Liquor and anything which is intoxicating.
- Dogs and pigs ( and their offspring )
- Dead body except the dead body of humans, fish and grasshoppers.
- Feces and urine.
- Any part of an animal separated when it was still alive except the feathers and wool or hair from animals that are halal to be eaten.
- Milk of all animals that are non halal to be eaten such as donkey’s milk and etc.
