Bedouin Owner's of Egypt's Western Desert

Prior to this trip I had no idea that the Bedouins literally own the desert. I've read about them being the traveling nomads throughout the middle eastern deserts, but when you travel the one desert highway south through Egypt, each of the five oasis towns belong to Bedouin families. When you stay in a hotel in the oasis, you are enjoying a part of the centuries of desert hospitality that is part of the Bedouin code.
This was written on one of the hotel walls -
"A guest is always welcome. The nomad believe any guest is a guest of God who is warmly welcomed as being brought by God....to be nice to this guest is to honor God."
