What is the ruling on prayer and the method of purification for a person who experiences the discharge of a liquid with the color and smell of feces, along with small pieces of it, after hemorrhoid surgery, which soils his clothes and forces him to change them for every prayer, and which exhausts him, especially during long working hours outside the home?

It is obligatory to perform istinja' (washing after defecation) and wash whatever has stained the clothes, and to perform wudu' (ablution) when anything comes out from the anus. Care should be taken by placing a tissue to prevent the spread of impurity. Avoiding impurity is a condition for the validity of prayer according to the majority of scholars. If you are unable to remove it, then pray according to your condition.
