Ruling on using sanitary waste flow to irrigate date palms
Question

                We have date palms which are growing near the sanitary waste flow.  Is it permissible to eat of their dates?
Praise be to Allah. 
          Yes, it is permissible to eat of the dates of the trees 
          which are irrigated with water from the sanitary waste flow because 
          if there is no taste or smell, that means that the najaasah (impurity) 
          has disappeared.
