180. If a ground that absorbs water—for example a ground that contains sand or gravel—becomes najis, it can be made ÔÁhir with qalÐl water.
181. If a floor which is made from stones, bricks or any hard material which does not absorb water, becomes najis, it can be made ÔÁhir with qalÐl water. However, the water should be poured to an extent that it starts to flow on the floor, and then if it is allowed to drain through a hole in the ground, the entire floor becomes ÔÁhir. If it is not allowed to drain, the area where the water gathers will remain najis. To make that area ÔÁhir, the water should be drawn with a ÔÁhir object. In this case, it is better that hole be dug for the water to collect in it. The water should then be drawn from it and the hole should be covered with earth.
182. If the exterior surface of salt-stone or anything similar becomes najis, it can be made ÔÁhir with qalÐl water, provided the water does not become muÃÁf water.
183. If a syrup made from najis sugar is used to make sugar cubes, the sugar cubes will not become ÔÁhir by placing them in kurr or flowing water.
