Fides et Leges Mohammaedis exhibitae ex Alkorani Manuscripto Duplici, Praemissis Institutionibus Arabicis.

Rare work of the Weimar-born Protestant theologian and Orientalist Theodoricus Hackspan (1607-1659), who after his studies in Jena, Altdorf and Helmstedt, first became a professor of Hebraistics, then of theology. "H. was a thorough and astute connoisseur of the Scriptures, and besides Sal. Glaß the most important Hebraist of his time. He had studied the rabbis thoroughly, and used the knowledge gained from them for theological science. He was also proficient in Arabic and Syriac "(ADB X, 299F).
Hackspan’s Grammar drawn from Koranic texts (“Not to be sneered at”: Schnurrer).
Theodor Hackspan professor of Hebrew at the university of Altdorf issued an Arabic grammar work, which ended in a series of excerpts from the Qur'an illustrating the tenets of Muslim belief. This 110 pages work is comprised of two parts of roughly equal length: an introduction to Arabic, and the eponymous Fides et Leges Mohammædis (‘The faith and laws of Muhammad’). The work ends with a seemingly unrelated one-page appendix enumerating Arabic astronomical terms.
