Environment is one of global issues humans are facing today. The worsening condition of global environmental cannot be apart from various problems from garbage, logging, and air pollution due to industrial or transportation activities as the main factors of the environmental crisis. The basic principles of ecology are to protect, maintain, utilize and preserve the environment for the life of future generations. In the context of power, the idea of ecology and environmental sovereignty is related between God, humans and nature. The results of this study showed that Islam is very concerned with these environmental issues as proven through many discussions contained in classical fiqh literature, such as discussion of thaharah (cleanliness), ihya al-mawat (opening the unused land), al-musaqat and al-muzara'ah (utilization of land belonging to others), laws related to the sale and purchase and ownership of water, fire and salt, the rights of pets and other issues related to the environment around humans.
