What are the rulings of ritual purity (taharah) related to prostatic fluid (madhy), and is it obligatory to repeat the prayer when in doubt about its emission, and how is the male organ purified from it, and is it permissible to use stones or other solid objects (istijmar) for purification from prostatic fluid?

The cure for waswas (obsessive whisperings) is to turn away from it and not pay attention to it. For when Satan sees the servant's steadfastness upon the truth, he retreats from him. Whenever Satan whispers to a person about an event occurring or madhy (pre-seminal fluid) exiting, he should not pay attention to these whisperings or investigate. Rather, he should purify himself and remove the impurity by pouring water until its substance and trace are gone, without scrubbing. If he leaves the restroom, performs ablution, and prays, he is not required to perform istinja' (cleaning after defecation/urination) again unless there is an actual impurity. He should not pay attention to doubts about the invalidation of his purification until certainty is attained. Wady (a thick, white discharge that may appear after urination) is impure, exits after urination, and necessitates istinja' and ablution. Madhy is a thin fluid that exits during foreplay or contemplation. It is impure and necessitates washing the male organ and performing ablution. Istijmar (using stones or similar materials for cleansing after defecation/urination) is sufficient for it by wiping the area three times or more with a stone or what takes its place, until purification is achieved.
