Abstract: Islam came into Ibadan land through trade relation that had been established between Hausa, Nupe and the Yoruba people. These category set of people exchanged kolanuts, animal skin, leather and grandnuts as medium of trade as far back as 14th and 15th centuries. Thus, the age long trade contact and communication between these mentioned groups of people further consolidated the advent and spread of Islam in Ibadan land. After the collapse of old Oyo Empire, many refuges migrated into Ibadan to settle because they were unsettled and displaced from their hometowns. By 1830, the dominant Yoruba and Hausa Muslim groups that settled in Ibadan land include the Oyo-Yoruba, Ife and Egba, Nupe and Bornu groups.
