Religion can play a considerable role in the protection of natural resources. The ecological spirituality movement is enjoying growing success crowned by the UNEP Faith for Earth initiative. In Muslim countries this movement is emerging. However, it has not yet been able to extensively exploit the law. Indeed, the particularity of the religion of Islam it is intertwined with the law. Consequently, this is an opportunity to be seized to strengthen environmental law. There are at least six reasons that explain the interest of the extension of Ecological Spirituality in the sphere of environmental law. These same reasons also explain the urgency of adopting a new research agenda in the field of environmental law in Muslim countries. One of these reasons is for example the Islamic finance movement which is growing globally and which could be inspiring for the Atmospheric Waqf paradigm and doctrine.
