This study is to assess the activities of the Du?at in Zazzau Emirate among the Maguzawa who accepted Islam. It was limited to only five local government areas in the emirate. The research presents the history of the emirate, tribe, religion and its locations in Kaduna state as well as it boundaries with other neighboring states. The research was able to view the meaning of Maguzawa, their culture and their locations in Zazzau Emirate. The concept of Da?wah was discussed in relation to non-Muslim, among others. Thus, Survey research design was used where three questionnaires were applied. The questionnaire covers the new converts among the Maguzawa, the teachers of Islamic education among the Maguzawa and then the Da?wah organizations/committees among the Maguzawa. Simple percentage was used in analyzing the data collected. The major findings of the research revealed that there is a significant number of Maguzawa that were converted to Islam from their paganism just as there is significant number of Maguzawa who were Christians and later converted to Islam. There are Da?wah committees/organizations conducting various Da?wah activities such as establishing Islamiyyah Schools and Mosques in which they conduct preaching and teachings of Islam. On the other hand, the new converts from the Maguzawa are in peaceful coexistence with the non-Muslims among them. In view of this, the research recommends that the Da?wah organizations need to coordinate their activities to avoid duplication and possible misunderstanding among them and there is need to use the Zakat proceeds and other forms of charity such as waqf from the Emirate to boost the activities of Da?wah and learning of Islam among the Maguzawa.
