184. The earth makes the sole of one's feet and shoes Pak, provided that the following four conditions are fulfilled:
The earth should be Pak.
The earth should be dry, as a precaution.
As an obligatory precaution, the najasat should have stuck from the earth.
If Najisul Ayn, like blood or urine, or something which has become najis,
like najis clay, is stuck on the sole of a foot, or a shoe, it will be Pak
only if it is cleared by walking on earth, or by rubbing the foot of the shoe
Therefore, if the Najisul Ayn vanishes by itself, and not by walking or rubbing on the ground, the foot or the sole will not be Pak by earth, as an obligatory precaution. And the earth should be dust or sand, or consisting of stones or laid with bricks; which means w alking on carpet, mats, green grass will not make the sole of feet or shoes Pak.
185. Walking over a tar road, or a wooden floor, will not make the najis sole of feet and shoes Pak. It is a matter of Ishkal.
186. In order to make the sole of one's feet or shoe Pak, it is better that one should walk a distance of at least fifteen arm-lengths or more, even if the najasat disappears by walking a lesser distance, or by rubbing one's foot on earth.
187. It is not necessary that the najis sole of one's feet or shoe are wet. They become Pak by walking on earth, even if they are dry.
188. When the najis sole of one's foot or shoe becomes Pak by walking on earth, the parts adjacent to it, which are usually blotched with mud, become Pak.
189. If a person moves on his hands and knees, and his hands or knees become najis, it is improbable that they become Pak by such movement. Similarly, the end of a stick, the bottom of an artificial leg, the shoe of quadruped and the wheels of a car or a cart etc. would not be Pak.
190. If after walking, the smell or colour of the najasat, or its invisible particles, remain in the sole of the feet or the shoe, there is no harm in it, although the recommended precaution is that one should walk so much, that these things also disappe ar.
191. The inner part of the shoe does not become Pak by walking, and similarly, the under part of the socks will not become Pak, unless it is made of skin or something similar, and one walks with it.
