This book aims to increase awareness about the current state of our environment and Islamic injunctions to play our part in protecting it as guardians of Creation ("We appointed you viceroys in the earth after them, that We might see how you behave.", Yunus/Jonah [10] 14). It includes some disconcerting facts about the current state of affairs, but hopes this will serve as inspiration for positive action (oftentimes saving money at the same time). It is organised around four key areas of Islamic life (beliefs, worship, transactions and moral character), reflecting on Islamic teachings, the current situation and then giving examples of practical ways we might please God by being a good guardian.
