I think some of the other contributer already stated the fallacie of this kaffirs objection. So why are you talking about a physician friend. Why not approach Hamza Trotsy or Adam Deen who can articulte this in english. They are easily approachable. HAve you read the post no 13? So why is he not reading the pdf. His insistant on physician is ridiculous. Generaly this approach is adoptedb by Salafist and Aithist or Evenglical pathological zionist Christian. Allahualam
