That is a LIE! Haj Amin el-Husseini, Mufti of Jerusalem, was also Hitler's ally! He may have even given Hitler the idea to kill all the Jews after the two of them met in Berlin in March 1941! Not to mention many of them were ready either to finish the Shoah or to watch it being done in 1948! And I haven't even gotten into all the anti-Jewish pogroms in Eretz Israel between Safed in 1834 and the whole land in 1936-39!
