Though athar of Ibn Abbas (Rd) has NOTHING to do with the possibility of another prophet coming in future , which Mawlana Qasim Nanotvee talks of in his book Tadhir al naas , we can still see the analysis of this athar.
This Israeli report which has been called weak/ shaadh can not justify any statement which Mawlana Qasim Nanotvee made. We have seen fatwa issued on mawlana Qasim Nanotvee in the above posts.
