Purity: Purification of Adjacent Areas Washed with Qalīl Water

Practical Laws of Islam as per the teachings of Ayatullah Sistani

Ruling 168

If an area of the body or clothing is washed with qalīl water, both the impure area and the area around it where water usually reaches during washing become pure. Therefore, it is not necessary to wash those adjoining areas separately. The same applies if a pure object is placed by the side of an impure object and water is poured over both of them. For example, to wash one impure finger with water, if water is poured on all the fingers and impure water as well as pure water reaches all of them, then by the impure finger becoming pure, all the fingers become pure.
