There is a Hadees of Rasul Allah (sm) which says "help your brother, even if he a Zalim or Mazloom". Upon this Sahabas asked Rasul Allah (sm), how can help our brother if he is Zalim??? Sayyadi Rasul Allah (sm) responded "stop him from the Zulm, this is your help to him" !!
That is why we talk to all those who support Deoband. Stop the Deobandis from supporting Modi and TTP !! They are Zalims and all those who are supporting Mushriks and Khawarij are also greatest of Zalims !!!
