Language is the main instrument in the wider spread and documentation of Islam and Islamic history in Africa and beyond. Historical development and rapid spread of Islam in African societies were historically accredited to African languages. The historic contact of the first Muslim generations with the Ethiopian emperor opens up the gate for the socio-linguistic development of translating Islamic dogma and messages into African languages. The Hausa factor in West African Islam is well noted in the writings of the early Muslim scholars. African linguistics contributions enhance the converts' literacy and develop a strong community of scholars of the highest historical relevance in the history of Islam in the African context. Africa is the home of about 2000 languages, Nigeria is with more than 556 languages, having Hausa leading the race with about 150 million speakers was rated as number 11 out of 7500 languages in the modern world as of 2022. Interestingly, about 85% of the Hausa native speakers are Muslims and about 69 percent of the Nigerian Muslim scholars are either Hausa natives or hausanized through Islamic activities in Hausaland. Thus, the spread of Islam in Africa was the handwork of African languages and not by the sword as alleged by the observers. My contact with Muslim scholars of various regions in Hausaland justified that, the technique of identification and naming Arabic alphabets are the same across the regions. In addition, the Ajami writing styles are the same. Hundreds of books and manuscripts are of the same orthography. These gave me the courage to investigate how it helps Islamic scholarship in the West African regions. This paper aims to study the role of Hausa Muslim scholars in the translation, naming, and adaptation of the 28 Arabic alphabets into the Hausa language which led to the innovation of Hausa Ajami writing and subsequent development of scholarship in the Hausaland. The paper would critically look into the Hausa-Arabic battle of alphabets treatment and the role of mother tongue in Islamic scholarship activities in West Africa Islam, with special emphasis on Hausa-speaking communities of West Africa.
