These "madaris" were probably a positive byproduct of the long history of Muslims’ interest in literary work. In ""The Islamic Literary Tradition in Ghana"", author Thomas Hodgkin enumerates the large literary contribution that was made by Dyula-Wangara Muslims to the history of not only the regions they found themselves in but also of West Africa as a whole. He cites al-Hajj Osmanu Eshaka Boyo of Kintampo as an “‘alim" with a wide range of Muslim connexions and an excellent grasp of local Islamic history” whose efforts brought together a great many Arabic manuscripts from around Ghana. These manuscripts, the "Isnad al-shuyukh wa’l-ulama", or "Kitab Ghunja", compiled by al-Hajj ‘Umar ibn Abi Bakr ibn ‘Uthman al-Kabbawi al-Kanawi al-Salaghawi of Kete-Krachi who Hodgkin describes as “the most interesting, and historically significant of the poets,” may now be found in the library of the Institute of African Studies of the University of Ghana.
