Conditions for Earth to Make Things Ṭāhir
Issue No.200- If the sole of one’s foot or shoe has become najis due to walking on najis earth, it will become ṭāhir by walking on earth or rubbing it against the ground after the original najāsah is removed, provided that the ground is ṭāhir and dry and consists of soil, stone or is paved with brick, cement or other similar things, but carpets, mats or grass will not suffice.
