Sweating while urinating

Q: What is the ruling if someone urinates or defecates, performs Istijmar (cleansing the private parts with hard material after urination or defecation), then they sweat, does this sweat make clothes Najis (impure)?

A: All praise be to Allah Alone, and peace and blessings be upon His Messenger, and his family and Companions. Istijmar must effectuate complete purification of the genital area; once the area is perfectly cleansed from urine or feces, then any perspiration from this area will not defile the clothes touching it, because through performance of this purification process the place is judged to be Tahir (pure).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
