I was going through Masayel and got question about this
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 of the thing which has become najis, touches a third thing, that t hird thing will also become najis. It is commonly held by the scholars, that a thing which has become najis transmits its najasat, but indefinite number of transmissions is improbable. In fact, after certain stage it is Pak. For example, if the right hand of a person becomes najis with urine, and then, while still wet, it touches his left hand, the left hand will also become najis. Now, if the left hand after having dried up, touches a wet cloth, that cloth will also become najis, but, if that cloth touc hes another wet thing, it cannot be said to be najis. In any case, if the wetness is so little, that it does not affect the other thing, then the Pak thing will not become najis, even if it had contacted the Najisul Ayn.
My que is what if the hand get najis by najis ul ayan and it touches something else like other hand and it doesn't dry and that water touches 4th thing.. is that 4th one najis ? (If according to above que water doesn't dried up)
