Does the expulsion of non-pathological fluids from the body, other than through the natural outlets (before or behind), invalidate ablution?
Chapter on What Nullifies Purification
Al-Mughni
Book of Purification
Primary text
That which exits the body from a non-outlet source is divided into pure and impure. Pure outflow does not invalidate ablution under any circumstance. Impure outflow invalidates ablution generally, according to one narration. This view is supported by 'Abd Allah ibn 'Abbas, 'Abd Allah ibn 'Umar, Sa'id ibn al-Musayyab, 'Alqamah, 'Ata', Qatadah, Al-Thawri, Ishaq, and the People of Opinion (Ashaab al-Ra'y). The evidence supporting invalidation rests upon the narration of Abu Ad-Darda', who mentioned that the Prophet (PBUH) vomited and performed ablution, which Thawban confirmed by stating he poured the water for the Prophet's ablution. Al-Tirmidhi authenticated this narration as the soundest in this chapter, and Ahmad confirmed its authenticity. Another supporting evidence is the narration from Ibn Jurayj's father, citing the Prophet (PBUH) saying, "If anyone regurgitates (qala'sa), let him perform ablution." Furthermore, this view is supported by the aforementioned Companions without known opposition in their era, suggesting scholarly consensus. Finally, since this outflow is subject to ritual purification, it invalidates ablution, analogous to outflow from the proper outlets.
Supporting text
Malik, Rabi'ah, Al-Shafi'i, Abu Thawr, and Ibn al-Mundhir do not obligate ablution for such outflow. Al-Makhul stated that ablution is only required for what exits the front or back passage, arguing that since the natural outlet remains intact while something exits elsewhere, the status of purity is not nullified. They argue further that there is no explicit text, and it cannot be analogized to the outflow from the proper outlets because the ruling there is not based on a known effective cause ('illah), and the status should not differ between small/large amounts or pure/impure states, unlike the latter case.
