Without the oil resources, Saudi Arabia would be even poorer than Somalia. But the oil money made them one of the richest countries in the world and using that money they changed the other countries as well. Here in India, funding from Wahabis in Saudi Arabia has radicalized the Muslims and this has happened all over South Asia, Africa and the Southeast Asia. With Saudi oil revenues going down due to low prices, now Qatar has taken this spot. The UAE on the other hand has stayed largely clear of this involvement. They even formalized their diplomatic relations with Israel recently.
