How a Pak thing becomes Najis

126. If a Pak thing touches a Najis thing and if either or both of them are so wet that the wetness of one reaches the other, the Pak thing will become Najis. Similarly, if the wetness is so less that it does not reaches each other, then the Pak thing will not become Najis.  

127. If a Pak thing touches a Najis thing and one doubts whether either or both of them were wet or not, the Pak thing does not become Najis.

128. If there are two things and one does not know which of them is Pak, and which is Najis, and later a damp Pak thing touches one of them, that thing does not become Najis. However, if it touches both the things then the portion which came into contact with them two will become Najis.

129. If the ground, cloth, or similar things are wet, then only that part will become Najis where Najasat reaches, and the remaining part will remain Pak. Same is the case with melon, cucumber etc.

130. When a syrup or ghee is in a fluid state, in a manner that if some quantity of it is removed, it does not leave an empty trace, the entire quantity will become Najis immediately when even their slightest part becomes Najis. But if it has solidified, and when some part of it is removed, a trace of emptiness is seen, then, only that part

will be Najis which has come in contact with Najasat, even if the empty trace gets filled up later. So, if the droppings of a rat fall on it, only that part will become Najis on which the droppings have fallen, and the rest will remain Pak.

131. If a fly or an insect sits on wet, Najis thing, and later sits on wet, Pak thing, the Pak thing will become Najis, if one is sure that the insect was carrying Najasat with it, and if one is not sure, then it remains Pak.

132. If a part of one's body which is perspiring becomes Najis, all those parts to which the sweat reaches, will also become Najis.

133. Phlegm which comes out of the throat or nose, the part with blood will be Najis, and the remaining part will be Pak. Hence, if these substances come out of the mouth, or the nose, the part about which one is sure that Najasat has reached, will be Najis, and the part about which one is doubtful whether Najasat has reached it or not, will be considered Pak.

134. If an ewer with a hole in its bottom, is placed on Najis ground, and the water inside the vessel continues to flow forcefully, it will not become Najis. However, if the water does not come out of ewer and allowing the Najis water which was collected under it to come into the contact of water present in ewer, the water present in ewer will also become Najis.

135. If a thing enters the body reaching Najasat, but has no trace of it when brought out of the body, it is Pak. Hence, if a needle or knife, or any other similar thing, is driven into the body and has no trace of Najasat when it is taken out later, it is not Najis. Same is the case with sputum and mucus of the nose, if it contacts blood within the body, but does not have any trace of blood when it comes out of the body.
