The vital need to answer this question illustrates the importance of the new trend in Islamic Sharia that believes modern questions require that the traditional jurisprudence be reconstructed on the basis of foundational ideas safeguarding the spirit of Islamic values in a manner capable of coping with modern life. Sharia is the guide to healthy life. So, it must provide answers to questions that emerge in the course of time. In answering these questions, the main ends Islam as a religion pursues for human life must be met while a clear path to healthy life is introduced. Emergent problems and modern requirements of life must not be viewed as dead ends for Sharia or an excuse for transgressing the red lines and replacing divine religious teachings with man-made doctrines. Dynamic understanding of religion and perpetual revision of methods of deriving Sharia law is a middle way. In this method, fixed Sharia basic principles are consulted in order to find suitable answers for new problems. It would not be an exaggeration to say that the majority of emergent questions relate to those parts of Sharia laws that concern social life of man in all its scientific, economic, political, and cultural dimensions. The reason is obvious; much development has taken place in these fields resulting in the drastic alteration of patterns of life that makes the old rules irrelevant. Among the new questions, the relation between Zakat as a piece of Sharia law in Islam with taxation as a pivotal constituent of the function of the state in human social life stands out as a crucial question since it connects a very sensitive modern issue with a very important principle of Sharia; the obligation to safeguard the limits God has set in Sharia.
