I don't know whether the Koran says anything about hating Jews, but if it does that part was certainly ignored until the mid-twentieth century

Examples of early Muslim antisemitism: 9th-century "persecution and outbreaks of violence"; 10th- and 11th-century antisemitic propaganda that "made Jews out to be untrustworthy, treacherous oppressors, and exploiters of Muslims". This propaganda "inspired outbreaks of violence and caused many casualties in Egypt". An 11th-century Moorish poem describes Jews as "a criminal people" and alleges that "society is nearing collapse on account of Jewish wealth and domination, their exploitation and betrayal of Muslims; that Jews worship the devil, physicians poison their patients, and Jews poison food and water as required by Judaism, and so on.
