This is the Gulf of Alaska ocean meeting the Pacific Ocean. Two oceans which do not mix. To give my next point more solidity, let’s not ask when this was discovered by explorers, let’s ask when was Alaska even discovered??
“Outsiders first discovered Alaska in 1741 when Danish explorer Vitus Jonassen Bering sighted it on a voyage from Siberia.”
That is approximately 270 years ago. However, did you know that almost 1400 yeas ago! Allah revealed to Prophet Muhamad -a man who grew up in Mecca/desert- verses about this phenomenon.
“And it is He who has released [simultaneously] the two seas, one fresh and sweet and one salty and bitter, and He placed between them a barrier and prohibiting partition.” 25:53.
“He released the two seas, meeting [side by side]. Between them is a barrier [so] neither of them transgresses.” 55-56:19.
This is one of the countless miracles of the Quran. If it’s not enough for you, then search the other hundreds that scholars have extracted until today.
Thank you Allah for this breathtaking Book.
