Prayer: Moisture from Animals with Unlawful Meat
Practical Laws of Islam as per the teachings of Ayatullah Sistani
Ruling 812
If saliva, nasal mucus, or any other moisture from an animal whose meat is unlawful to eat, such as a cat, is on the body or clothing of someone performing prayers and it is wet, his prayers are invalid. However, his prayers are valid if it has dried up and the actual substance has been removed.
