Is the white, viscous liquid that exits with urine during defecation, and which becomes clear and viscous after finishing, considered viscous wady like semen? How is it purified, and what is the method for washing the hand if it is afflicted with impurity?

If what exits before or after urination without lust is al-wadi, then its ruling is the same as urine in terms of nullifying ablution and the obligation to wash the affected area. Some jurists have mentioned that al-wadi can be viscous. Purifying a hand affected by impurity is done by removing the substance of the impurity, then pouring water over it until no color or odor remains. The removal of color or odor is not a condition if it is difficult to achieve.
