Does inserting something into either of the two passages—such as using a rectal suppository—nullify ablution?

Using suppositories rectally invalidates the fast according to the majority of scholars (Shafi'is, Hanbalis, and the well-known opinion among Hanafis and Malikis) if it involves a liquid, according to the Malikis. However, Ibn Taymiyyah holds that it does not break the fast. Inserting anything into the anus invalidates ablution (wudu').
