The Lawgiver or the discourse of the jurists refers to the technical Sharia subject [not the linguistic one; likewise, everything that has both a Sharia and a linguistic subject, the absolute use of the term refers to the technical Sharia subject] such as wudu' (ablution), prayer, fasting, zakat, hajj, and the like, because the apparent intent of the Lawgiver is to speak according to his specific technical definitions.

The Prophet -may Allah bless him and grant him peace- was asked about performing wudu' with seawater, and he said: "It is the purifier (al-tahur), its water is lawful, its dead are lawful." And if it were not
