Sulaiman Abdul Aziz Al Rajhi

The Al Rajhi family is considered, by most in Saudi Arabia, as the country's wealthiest non-royals, and among the world's leading philanthropists.

He established the Sulaiman Al Rajhi University in his hometown, a non profit university. The university's main focus is on health and Islamic banking, but contains other faculties as well.

In May 2011, he announced he was donating most of his $7.7 billion fortune to charity.

Following the September 11 attacks, Sulaiman bin Abdulaziz Al Rajhi came under scrutiny after his name was identified among the alleged early financial benefactors of al-Qaeda on a document known as the “Golden Chain”, reportedly seized from al-Qaeda in 1992. The U.S. Senate's 2012 investigation into HSBC's handling of money-laundering and terrorist-financing risks also discussed Al Rajhi Bank, noting allegations of links to terrorist financing and identifying Al Rajhi as an early financial benefactor of al-Qaeda.

Al Rajhi was subsequently named as a defendant in litigation brought by families and estates of September 11 victims alleging that various individuals and financial institutions had provided support to al-Qaeda. In 2013, the U.S. Court of Appeals for the Second Circuit affirmed the dismissal of the claims against Al Rajhi on the ground that the plaintiffs had failed to establish personal jurisdiction over him in the United States. The court did not make a finding that he had knowingly or intentionally supported terrorism; rather, it held that the allegations were insufficient to establish the court's jurisdiction.
