The 82 mosques in Harar have served a religious and social function for society. Once a day men go and pray in the mosque while the women pray at home, though construction has begun to areas where women can pray as well.

Islamic Orthodox The Orientalist notion defined Islamic Orthodoxy "as the point of departure that consequently measured other practices and beliefs as syncretistic or pre-Islamic." J. Spencer Trimingham the author of Islam in Ethiopia examined the impacts of Islam in the country and arranged his analysis by a hierarchical typology of different forms of appropriation categorized as an "orthodox system." Institutions of Islamic learning in Ethiopia were maintaining an Islamic Orthodoxy within the community. Muslim land rights Muslims were one of the marginalized groups that were not allowed access to land until the 1974 revolution. The revolution brought forth major changes to the socio-political and religious position of Ethiopian Muslims. In Gojjam, most Muslims did not have access to land, but had ways to get around it. They could rent, buy land, or enter in a crop sharing verbal agreement with the landowner. Muslims did not have the right to own, administer, or inherit land they simply were only allowed to live as tenants. If a verbal agreement was not an option, another way Muslims were able to acquire land was by clearing out unoccupied land and settling there, but only if they were able to offer some type of service to the balebat. Muslims were marginalised in Ethiopia, but particularly in Gojjam. Rise of Salafism/Wahhabism Salafism/Wahhabism is derived from al-salaf, signifying a link back to what is known as pure and authentic Islam.
