Handbook attempts to find answers to some questions concerning the definition and characteristics of the ethical system in Islam. What is its goal and how do its rules and practices ensure welfare for individuals and society? Are the moral principles universal and invariable or do they change and adapt with the social changes of communities and progress in science and technology? Is the present generation accountable for the welfare of future generations? Where is the boundary between law and ethics and who guarantees their adoption and implementation?
