I heard about this 30 years ago.
There has been a FRESH WATER PEARL industry in Bahrain for eons. The fresh water rain in Yeman (some of it) washes down through the sand and travel across the Saudi countryside through these underground river beds and comes out at the BASE of the Saudi gulf-side land into the so-salty gulf. It's fresh water.

The Bahrainis had pearls there for years, FRESH water pearls, that is, ODD sized and shaped. Cost a friggin' fortune because the awl bidness is killin' off the pearls. Imagine, Arab pearl divers, all men, of course.

The gulf used to have hamur (big white fish) and TONS of delicious shrimp. The Saudis used to build these triangular fish traps and just let the tides do their "fishing."

and of course we all know about the huge project in Libya to pump water out of the desert. I guess at one time or another there has been running water everywhere.

Arabian Desert

Per Wiki: "Map of the Arabian Desert. Ecoregions as delineated by the WWF. Satellite image from NASA. The yellow line encloses the ecoregion called "Arabian Desert and East Sahero-Arabian xeric shrublands",[1] and two smaller, closely related ecoregions called "Persian Gulf desert and semi-desert"[2] and "Red Sea Nubo-Sindian tropical desert and semi-desert".[3] National boundaries are shown in black."

Well, surprise, surprise. NOT. I live in the Coachella Valley (Palm Springs area) of Southern California, also known as the Sonoran Desert or Colorado Desert. At one time, it was underwater. One can dig and find sea shells.

Quite a few years ago, I purchased a new home on a mesa above San Diego Stadium. So, it was about 50 to 75 feet above sea level. Every place I dug in the yard when planting my garden, I found sea shells.

Everything was great there before Global Warming

I wonder how the average reader is supposed to glean any useful information from postage stamp, minuscule illustrations with illegible detail?
