Idris Alooma (1571–1603), although a large part of that country still adhered to traditional religions. Alooma furthered the cause of Islam in the country by introducing Islamic courts, establishing mosques, and setting up a hostel in Makkah, the Islamic pilgrimage destination, for Kanuris. In Hausaland, particularly Kano, Islam is noted to have penetrated the territory in the fourteenth century from West African traders who were the Mande people Muslims from the Senegalese basin and Muslim traders from Mali Empire. Muhammed Rumfa (1463 - 1499) was the first ruler to convert to Islam in Hausaland. It had spread to the major cities of the northern part of the country by the 16th century, later moving into the countryside and towards the Middle Belt uplands. However, there are some claims for an earlier arrival.

Islam in Southwestern Nigeria Islam also came to the southwestern Yoruba-speaking areas during the time of the Mali Empire. In his Movements of Islam in face of the Empires and Kingdoms in Yorubaland, Sheikh Dr. Abu-Abdullah Adelabu supported his claims on early arrival of Islam in the southwestern Nigeria by citing the Arab anthropologist Abduhu Badawi, who argued that the
