It is not for the sun to overtake the moon, nor doth the night outstrip the day. They float each in an orbit. http://wikiislam.net/wiki/Compendium_of_Muslim_Texts - Qur'an http://www.usc.edu/org/cmje/religious-texts/quran/verses/036-qmt.php#036.040 - 36:40 Some apologists try to explain away the Qur'anic description of the sun moving in an orbit as a reference to our sun orbiting the black hole at the center of the milky way galaxy every 225 million years. This is an http://en.wikipedia.org/wiki/Ad_hoc_hypothesis - Ad hoc hypothesis , of no relevance to human time scales, and nothing from the text implies that the sun is orbiting anything other than the earth. If the author had knowledge of the sun orbiting a black hole then it is conspicuous that he never mentions it explicitly nor in any way differentiates the sun's orbit from that of the moon. In the Qur'an, the moon and the sun orbit the earth together. There is no distinction made between the moon, which actually revolves around the earth, and the sun which only appears to revolve around the earth when in fact the sun's apparent movement through the sky is a product of the rotation of the earth around its axis.

Permanent Barrier between Fresh and Salt Water Main Article: http://wikiislam.net/wiki/Meeting_of_Fresh_and_Salt_Water_in_the_Quran - Meeting of Fresh and Salt Water in the Quran When a fresh water river flows into the sea or ocean, there is a transition region in between. This transition region is called an http://en.wikipedia.org/wiki/estuary - estuary where the fresh water remains temporarily separated from the salt water. However, this separation is not absolute (thus cannot be described as a "barrier"), is not permanent, and the different salinity levels between the two bodies of water eventually homogenize. The Qur'an however erroneously says that the seperation between the two types of water is absolute and permanent. It is He Who has let free the two bodies of flowing water: One palatable and sweet, and the other salt and bitter; yet has He made a barrier between them, a partition that is forbidden to be passed.

Ever been to the sea side?
