The Quran has no contradictions with Science

My opponent knows this, but I'll say it to our viewers just to be clear: The Quran was revealed in Arabic. It has been preserved for centuries till the present. Nowadays, there are multiple translations of the Quran to English. The translations depend heavily on the translator's understanding of the verses for they can be ambiguous at times. Back to our topic. Let's analyze the original text in the Quran. The verse mentions a barrier using the word "Barzakh" and described it using two following words "Hijran mahjoora (حجراً محجوراً)". Let's first look at "Barzakh" which is an odd word to use to describe a barrier. To translate "barrier" to Arabic you can use the following words: - Ha'el (حائل) - Hajez (حاجز) - Mane' (مانع) - Sadd (سد) - Aa'ek (عائق) - And finally Barzakh (برزخ), which is the one used in the verse. I put the word Barzakh in the end because it is the most uncommonly used word to describe a barrier. When I hear "Barzakh", I don't picture a brick wall. That would be thinking too literal. Actually, the word "Barzakh" is used more commonly in a different context, and this may seem strange but I assure you I'm not making this up. The word "Barzakh" is used to describe the in-between phase after death and before the afterlife. We believe the soul will be living a transitional phase before the afterlife called a "barzakh life". To be honest, I'm learning more about my religion from my opponent. I really never made this connection.To summerize, the official definition of "Barzakh" in Arabic is: Something between two things. It doesn't necessarily mean that it's a barrier that forbids anything from crossing. Also, the model of the estuary that my opponent mentioned fits perfectly, until now, in the verse, where the estuary is the barzakh. Now let's go to the second part, the part that describes the barzakh of being a "Hijran Mahjoora". This is the part where some translators got the "forbidding of passing of anything" idea from. To be honest, it could be a correct translation. I don't blame the translators. But the words of the verse in Arabic are not that explicit. If you want to explicitly say "the passing of things is forbidden", You would say:" Yamnaa' muroor al-ashyaa' " (يمنع مرور الأشياء). That's not what the Quran says. The Quran says "Hijran Mahjoora" which is difficult to define in one sentence. It indicates a sense of boundaries and borders in a slightly more abstract way because the context here is waters meeting so it would be stupid to think of it as an objective barrier like a brick wall. But we still need to search for some kind of bordering in the estuaries on some level. Otherwise, the verse will be false. So let's see what science really tells us about estuaries: 1- The barrier is a barrier of salt. I will quote one of Wikipedia's sources on the topic speaking specifically about the salt wedge estuary ( Tomczak, M. (2000). "Oceanography Notes Ch. 12: Estuaries". Retrieved 30 November 2006. Link: http://www.es.flinders.edu.au... ). It says: " The fresh water flows out over the sea water in a thin layer. All mixing is restricted to the thin transition layer between the fresh water at the top and the "wedge" of salt water underneath. Vertical salinity profiles therefore show zero salinity at the surface and oceanic salinity near the bottom all along the estuary. The depth of the interface decreases slowly as the outer end of the estuary is approached (Figure 12.1)" Here's the figure:http://www.es.flinders.edu.au... In the figure, the concentrations graph is not linear. It gets very steap at one point indicating a subtle difference and therefore could be called a border. See also the vertically mixed estuary here: http://www.es.flinders.edu.au... 2- The estuary is considered to be an ecosystem that is distinctive from the ocean and the river. It has a different set of lifeforms that can only survive in an estuary. See examples here: http://www.onr.navy.mil... So in some way it's an enclosed space for many lifeforms, not by having an objective barrier, but rather an abstract one. And this fits with Quran when God -almighty- says: { Hijran Mahjoora }. It is known that every marine creature is used to a certain level of salinity. If you take a freshwater fish and throw it in the ocean, it will die in a matter of minutes. In an estuary, there are kinds of creatures that if they left will feel very discomforted or could die.To summerize in three points:- The verse doesn't explicitly mention an objective barrier nor it mentions explicitly an abstract one. It is open to interpretation.- There is some level of separation and borderlining proven in the science of estuaries. Salt and some marine life are clear examples.- The nature of estuaries being a transitional phase can be linked to the word "Barzakh" mentioned in the verse that can easily accommodate the meaning.
