Sulaiman Abdul Aziz Al Rajhi

My experiment in money exchange was the temptation to set up a bank. The absence of any Islamic banking was also another factor in establishing Al-Rajhi Bank, which is now the world's biggest Islamic lender by market value.

Usually, people in the Islamic world set aside one-third or one-fourth of their wealth for endowment, and that will be effective only after their death. But in my case, I decided to implement this decision in my lifetime itself.
