Does civet, which is extracted from an animal resembling a cat and used in perfumes and hair treatments, invalidate ablution (wudu') when applied to the face or head, especially since it is extracted from a gland near the two excretory orifices, and it is difficult to ensure that it has not mixed with anything from them?

Scholars have differed regarding the purity of civet musk. The majority of jurists (Hanafis, Shafi'is, and Hanbalis) are of the opinion that it is pure because it has transformed into a pleasant substance, and because it is the perspiration of a pure animal, concerning which a text was revealed regarding the purity of its leftover drink (the cat). On the other hand, the Hanbalis, in another opinion, considered it impure because it is the perspiration of a wild, non-edible animal. The more accurate view is to consider it pure, based on the two reasons mentioned, and in accordance with the rule of transformation (istihalah), which stipulates the purity of an impure thing if it transforms into another substance and loses its characteristics of impurity.
