Saudi Arabian corporate figure and billionaire Sulaiman Al Rajhi has an estimated net worth of $2.1 billion as of April 2015, according to Forbes. He is the fourth wealthiest person in Saudi Arabia and is ranked 198th in the list of World Billionaires according to Forbes.

Sheikh Sulaiman bin Abdul-Aziz Al-Rajhi has built his estimated net worth of $6 billion as the chairman of Al Rahji Bank, one of the largest companies in Saudi Arabia and one of the largest Islamic banks in the world. He co-founded the bank along with his brothers Abdullah, Mohammed, and the late Saleh after they got the permission to open the first Islamic bank in Saudi Arabia. It is said to observe religious tenet, which is the ban on interest. It has also helped the country’s immigrants to send their earnings home to places such as Indonesia and Pakistan.

Recently, Al Rajhi has distributed his wealth among his children and set aside a portion intended for his charity project. He actively runs his SAAR Foundation that has funded anti-hunger efforts and education in Saudi Arabia. In 2000, it dissolved its U.S. branch, which had reportedly been linked to the funding of alleged terrorists.

Despite donating a bulk of his fortune to charity, and his recent claims in an interview that he is a man who only owns his dresses, he is still listed on the Saudi stock exchange as the owner of nearly 20% of Al Rajhi Bank (worth more than $5 billion). This also makes him as one of the richest and most affluent people in Saudi Arabia.
