What is the ruling on yellowish discharge and light yellow or white discharge with a continuous odor throughout the month, except for the menstrual period? Is it impure? And what is the correct method of purification (istinja') from it if it is impure and continuous?

This yellowish discharge is impure, and one must cleanse oneself from it by washing the affected area until it is predominantly believed that the impurity has been removed. The water that separates from the cleansing process is pure if it has not changed due to the impurity. If the yellowish discharge is continuous, the woman should take precautions, such as tying a cloth or similar item, and perform ablution after the entry of the prayer time, then pray as much as she wishes until that time exits.
