Then said Joab to Cushi, Go tell the king what thou hast seen. And Cushi bowed himself unto Joab, and ran.
2 Samuel 18:21

Veteran journalist Haviv Kanaan published an article in Haaretz in 1970 in which he reviewed the senior Muslim clergyman's actions in 1942, when the Jewish community in then-British Mandate Palestine was preparing for the possibility of a Nazi invasion. Kanaan said that in 1968, while researching his article, he met with Faiz Bay Idrisi, a senior Arab officer in the Mandate Police, who spoke of al-Husseini's intention to build a crematorium in the northwest Samarian hills.

"Haj Amin Husseini was gearing to enter Jerusalem at the head of the Muslim Arab Legion squadron he'd created for the Third Reich. The mufti's plan was to build a huge Auschwitz-like crematorium in the Dotan Valley, near Nablus, to which Jews from Palestine, Iraq, Egypt, Yemen, Syria, Lebanon, and North Africa would be imprisoned and exterminated, just like the Jews in the death camps in Europe."
