Book excerpt: Judaism, Christianity and Islam all impose obligations and constraints upon the rightful use of wealth and earthly resources. All three of these religions have well-researched views on the acceptability of practices such as usury but the principles and practices of other, non-interest, financial instruments are less well known. This book examines each of these three major world faiths, considering their teachings, social precepts and economic frameworks, which are set out as a guide for the financial dealings and economic behaviour of their adherents.
