The Koran was first translated into Latin in the 1140s

Evidence

In 1142–43 Peter traveled to Spain and assembled a team of translators. He had Robert Ketton produce a full, Latin version of the Koran, which was subsequently given extensive marginal annotations; it is the first translation of the Koran into Latin, indeed probably the first complete translation into any language. — John V. Tolan, Saracens, 835
