Thirteenth-century Dominican missionaries were formally trained in Arabic and Jewish scriptures

Evidence

In that year the Dominican provincial chapter of Toledo established a school of Arabic for eight of its friars, including Ramon Martí. Martí was not only educated in Arabic and Hebrew but also studied the Talmud and works of Arabic philosophy: al-Ghazâlî, Ibn Sînâ, al-Razi, and others. — John V. Tolan, Saracens, 1184
