What is the ruling on the discharge of customary substances from the two passages (urinary and anal)?

Primary text

The discharge of customary substances from the two passages, such as urine, feces, semen (*maniyy*), pre-ejaculatory fluid (*madhy*), post-ejaculatory fluid (*wady*), and flatulence (*reeh*), invalidates ablution (*wudu*) by consensus (*ijma'*). Consensus among scholars affirms that the exit of feces from the anus, urine from the male organ or female passage, the exit of *madhy*, and the exit of flatulence from the anus are all acts that nullify ritual purity and necessitate *wudu*. Ibn al-Mundhir documented this consensus among the people of knowledge.
