The Mufti also wrote a pamphlet for the 13th SS "Handschar" division, translated as "Islam i Zidovstvo" (Islam and Judaism) which closed with a quotation from Bukhari-Muslim by Abu Khurreira that states: "The Day of Judgement will come, when the Muslims will crush the Jews completely: And when every tree behind which a Jew hides will say: 'There is a Jew behind me, Kill him!". Some accounts have alleged that the Handschar was responsible for killing 90% of Bosnian Jews. However, Handschar units were deployed only after most of the Jews in Croatia had been deported or exterminated by the Ustase regime. One report, however, of a Handschar patrol murdering some Jewish civilians in Zvornik in April 1944 after their real identity was revealed, is plausible.
