In studies concerning Islam and gender in West Africa, the expertise of women in Islamic esoteric practices is often overlooked. These practices, that include divination, dream interpretation and prayer sessions, are central in politics, economics and the daily life of most West Africans. Furthermore, their products (such as amulets) and their practitioners (marabouts) travel to Europe, the United States, and the Middle East. Despite the importance of Islamic esoteric practices in West Africa and the rest of the world, they are understudied. In this article, I focus upon the life and work of two marabout women living in Dakar: Ndeye Meissa Ndiaye and Coumba Keita. Their position is exceptional: Islamic esoteric knowledge is a particularly male-dominated field. This article describes how two women's Islamic esoteric expertise is negotiated, legitimated and publicly recognized in Dakar.
