the male member, that it does not nullify it; because the bladder does not have an opening to the interior (al-jawf), nor did our companions classify it as an interior, nor did they invalidate the fast due to an enema in it. We know of no existence for this, nor do we know of its existence regarding anyone. It has been said: its existence can be known by a person feeling movement within his male member. This is not correct, for certainty is not achieved by this, and ritual purity is not nullified by doubt. However, if its existence were established with certainty, it would nullify ritual purity because it is something issuing from one of the two passages; therefore, it nullifies it, by analogy to all other emissions.

Section: If one drips oil into his urethra and it subsequently exits, it nullifies wudu', because it is something issuing from a passage, and it is never free from an impure moisture that accompanies it, thus wudu' is nullified by it, just as if it had exited on its own. If one inserted cotton into his male member and it then exited with moisture on it, it nullifies wudu', because if it had exited alone it would have nullified it, so it is the same if it exits with something else. If it exits dry, there are two opinions: one of them is that it nullifies, because it is something issuing from a passage, thus resembling other emissions. The second is that it does not nullify, because there is no opening between the bladder and the interior, so it is not considered as having issued from the interior. If one takes an enema into his posterior, and parts return and exit from the private part, it nullifies wudu'. Likewise, if he has intercourse with his wife and does not penetrate the private part, but his fluid moves and enters the private part then exits, it nullifies wudu', and both parties must perform istinja', because it is something issuing from a passage and is not free from moisture that accompanies it from the private part. If they do not know whether anything exited from it, there are two possible opinions: one of them is that it nullifies in both cases, because the prevailing state is that it is not free from exiting, so it nullifies, like sleep. The second is that it does not nullify, because ritual purity is certain, and we do not depart from it due to doubt. However, if the person taking the enema had inserted the tip of the syringe and then removed it, it nullifies wudu'. Likewise, if he inserted a probe or something else into it and then removed it, it nullifies wudu', because it is something issuing from a passage; therefore, it nullifies it, like any other emission.
