Rainwater Which Comes in to Contact with an Original Najāsah
Issue No.44- If there is original najāsah on the earth or the roof of a building, and rain falls on it, it will be necessary, as an obligatory precaution, to avoid the water. However, the amount that has not fallen on the najāsah is ṭāhir, and if it is mixed with that which has come in to contact with the najāsah and flows down the rain drain pipe, it will be ṭāhir too.
