The article explores how the process of appropriating the discourse of 'development' by Muslim organisations and 'NGOs' might be a factor in the construction of new forms/contexts of Muslim political participation in Senegal. By promoting 'Islamic development', Muslim organisations have moved into a discursive field that was previously the fief of the secular state. It is shown how the discourse of 'development' and 'Islam' and the interplay between them are functional in the context of competition and negotiation amongst political actors in Senegal. The result observed is very complex and multifaceted. By claiming 'Islamic development' and playing with the content of these two concepts according to the powerpolitical context, 'Muslim' organisations and personalities claim political space from the 'secular' state as well as from each other.
