Question
What is the minimum requirement for rinsing the mouth? Is it necessary for the validity of inhaling water and rinsing the mouth to remove food stuck in the gums and mucus in the nose?
Answer
I say, and with God's success: rinsing is the act of bringing water into the mouth even if some food remains, and inhaling is the act of bringing water into the nose even if all the mucus is not removed, and God knows best.
