How can one be content with merely cleaning oneself with tissues after urinating outside the home, knowing that urine might extend beyond the urethral opening to the glans, and that the scrotum might touch the glans and become impure?

Istijmar (cleaning with stones or similar dry material) is sufficient for purification, and its location is considered pure by many scholars. Doubting the transfer of impurity does not matter, because the original state is the absence of impurity transfer. Istijmar is sufficient, even if urine goes beyond the glans. Some scholars have permitted istijmar on the two صفحات (cheeks of the buttocks), the glans, and other areas. This opinion is permissible to act upon for those afflicted with obsessive-compulsive disorder (waswas).
