The Ruling of Well Water and Its Conditions to Be Muṭahhir
Issue No.49- The water of a well is ṭāhir and makes najis things ṭāhir, even if it is less than kurr. And if a najis thing which does not contain an original najāsah is washed with it, it becomes ṭāhir, provided that it does not take on the colour, smell or taste of the original najāsah.
