And this attack and other attacks on the Jewish community in 1920, 1921, 1929, were instigated by a call of the Mufti of Jerusalem Haj Amin al-Husseini, who was later sought for war crimes in the Nuremberg trials because he had a central role in fomenting the final solution. He flew to Berlin. And Haj Amin al-Husseini went to Hitler and said, "If you expel them, they'll all come here." "So what should I do with them?" he asked. He said, "Burn them." And he was sought in, during the Nuremberg trials for prosecution.

In my opinion, the Grand Mufti, who has been in Berlin since 1941, played a role in the decision of the German government to exterminate the European Jews, the importance of which must not be disregarded. He has repeatedly suggested to the various authorities with whom he has been in contact, above all before Hitler, Ribbentrop and Himmler, the extermination of European Jewry. He considered this as a comfortable solution for the Palestine problem.

The Mufti was one of the initiators of the systematic extermination of European Jewry and had been a collaborator and advisor of Eichmann and Himmler in execution of this plan. He was one of Eichmann's best friends and had constantly incited him to accelerate the extermination measures. I heard him say, accompanied by Eichmann, he had visited incognito the gas chamber of Auschwitz.
