When he mentioned the points over which he made the prayers of Mubahala and said that they are all lies, from amongst that was that "the State views everyone who fights against it to be fighting against Islam and that they have left the religion".
So how has he confirmed what he had himself denied previously?! And he confirmed the truth of what his opponent has said! And how did he have the courage to invoke prayers of curses for the issues which he himself contradicted?! (By saying) "We do not make Takfeer on those who fight against us", and then (contradicted it by saying) "the one who fights us has fallen into Kufr"!!! (1)
