Fritz Grobba wrote on 17 July 1942 that the Mufti himself had visited Oranienburg concentration camp and that "the Jews aroused particular interest among the Arabs. ... It all made a very favorable impression on the Arabs." This is cited in confirmation of the view that an associate of al-Husseini's together with three associates of the former Iraqi Prime Minister certainly must have visited the Sachsenhausen concentration camp as part of a German secret police "training course" in July 1942. At the time, the Sachsenhausen camp, set up by the Nazi authorities as a "model camp" to be shown off to both domestic and foreign visitors, housed large numbers of Jews, but was only transformed into a death camp in the following year. The camp was presented during their tour as a re-educational institution, and they were shown the high quality of objects made by inmates, and happy Russian prisoners who, reformed to fight Bolshevism, were paraded, singing, in sprightly new uniforms. They left the camp very favourably impressed by its programme of educational indoctrination. In his memoirs, he recalls Himmler telling him how shocked he was to observe Jewish kapos abusing fellow Jews and that Himmler claimed he had the culprits punished.
