two funny blunders in the Quran

monfret

And of every thing We have created pairs: 
That ye may receive instruction. 
-- Sura 51:49

another one is the claim there is a barrier between salt and fresh water,this is proven false by vertically homogenous estuaries and brackish water.islamic propoganda will show videos of salt water not mixing immediately with salt water due to differing pressure conditions.do not be fooled.salt and fresh water mix all the time.:

سُوۡرَةُ الرَّحمٰن

بِسۡمِ ٱللهِ ٱلرَّحۡمَـٰنِ ٱلرَّحِيمِ

رَبُّ ٱلۡمَشۡرِقَيۡنِ وَرَبُّ ٱلۡمَغۡرِبَيۡنِ (١٧)

فَبِأَىِّ ءَالَآءِ رَبِّكُمَا تُكَذِّبَانِ (١٨)

مَرَجَ ٱلۡبَحۡرَيۡنِ يَلۡتَقِيَانِ (١٩)

بَيۡنَہُمَا بَرۡزَخٌ۬ لَّا يَبۡغِيَانِ (٢٠)

Ar-Rahman

In the name of Allah, the Beneficent, the Merciful

Lord of the two Easts, and Lord of the two Wests! (17)

Which is it, of the favours of your Lord, that ye deny? (18)

He hath loosed the two seas. They meet. (19)

There is a barrier between them. They encroach not (one upon the other). (20)

Qur'an 55:17-20

سُوۡرَةُ الفُرقان

بِسۡمِ ٱللهِ ٱلرَّحۡمَـٰنِ ٱلرَّحِيمِ

۞ وَهُوَ ٱلَّذِى مَرَجَ ٱلۡبَحۡرَيۡنِ هَـٰذَا عَذۡبٌ۬ فُرَاتٌ۬ وَهَـٰذَا مِلۡحٌ أُجَاجٌ۬ وَجَعَلَ بَيۡنَہُمَا بَرۡزَخً۬ا وَحِجۡرً۬ا مَّحۡجُورً۬ا (٥٣

Al-Furqan

In the name of Allah, the Beneficent, the Merciful

And He it is Who hath given independence to the two seas (though they meet); one palatable, sweet, and the other saltish, bitter; and hath set a bar and a 

forbidding ban between them. (53)
