This is Al Rajhi Bank headquarters, being built on behalf of the Al Rajhi family, said to be the country’s wealthiest non-royals and also among the world’s leading philanthropists. There is quite an interesting video and text at https://vimeo.com/94132186 which says the tower "... draws from the regional context by creating four monolithic piers or cores to shield the crystalline glass tower from the inclement weather. ... While visually creating a strong landmark, the design makes a statement akin to entering a tall & narrow mountain pass to arrive at an oasis."
