Weird natural phenomenon in Saudi Arabia's Empty Quarter desert

There is a prophecy that one of the sign of the end of times is that the land of Arabs will turn into rivers and gardens as it was before.

The incredible footage below appears to show a river in the middle of the desert made of sand.

Viewers aren’t exactly sure what caused this outrageous natural phenomenon but it is said the region was hit by a rain and ice storm last November 2015, which led to a frozen river of ice water raging through the desert.

As a man watches the phenomenon in disbelief, he scoops up a hand full from the river and we can see the river is actually made up of countless small pebbles of hail.

Whether the phenomenon is caused by a rain and hail storm remains a question but everyone can agree that it is very strange to say the least.
