Dr. Shabbir I think that you misunderstood my last post. I am very appreciative for the work that Ourbeacon has done to clarify these terms, however I was not referring to reinventing these duties that the Qur'an prescribes for Mankind since as you state they are clearly presented in the Qur'an and just need to be understood. There is no need to reinvent these concepts but there is definitely always a need for innovations, this is what I was mainly referring to when I was saying that deen is dynamic. These terms yes are clear but they allow for innovation of what should be done for example throughout different time periods, for example in the Hajj pilgrimage prescribed as a duty for mankind the Qur'an simply states the mankind must unite to cleanse their vices in society. Mankind must come up with the ways that they want to solve their societal problems and which ones they should be addressed, thus innovative ideas on economic policies, environmental policies and even innovative inventions in certain areas of science and technology could be addressed. Since the Qur'an did not specify the specific ways the societal issues should be addressed and invites all humanity to the conference it allows for more innovative and dynamic ways mankind can solve their issues. Such a gathering would be much more efficient and beneficial to mankind than the UN Global Summits which not only are very selective in the people that are invited but are also very stringent in the issues which are discussed. In my writing on the Yaum Ad-Deen, Im simply writing about what has already been clarified but more extensively, since I feel that some people who come from N2I backgrounds cannot see the big picture unless ones explains these concepts to them extensively then they begin to see the huge global and societal potential of these terms hold. I will also discuss this period from many other viewpoints including its historical point of view. My main point is not only should we clarify these concepts to others who don't understand them, we should also place them in the context of innovative ideas that they can be applied with today. If we just clarify these concepts and dont apply innovative concepts and activities to these duties then these concepts such as Salat, Saum and Hajj just remain concepts who in the minds of some is clear but not to others, but when applied with new innovations,ideas and constructive activies these clarified concepts not only become more acceptable to the N21 muslims but also non-muslims. There is indeed no need to reinvent the wheel but what has been holding Islam back is that not only does the Muslim world not understand the Qur'an but they also lack constructive and innovative thinking, which is very much needed to implement the Qur'an effectively in societies. This however was not the problem in the first century of the Muslim Civilization as these terms and concepts were fresh and clear in peoples minds. Once Innovative thinking in many areas of science,technology,education and civil society practices take hold with the light of the Qur'an humanity will begin to witness unprecedented development and progress in the future.
