At Saturna Capital and the Amana Mutual Funds Trust, they endeavor to align their investments with their principles.

Their Funds favor companies with low price-to-earnings multiples, strong balance sheets, and proven businesses. They follow a value-oriented approach consistent with Islamic finance principles. Generally, these principles require that investors avoid interest and investments in businesses such as liquor, pornography, gambling, and banks. The Funds avoid bonds and other conventional fixed-income securities.

Saturna Capital selects investments in companies that to its knowledge do not violate the requirements of the Islamic faith at the time of investment. To ensure that investments continue to meet the requirements of the Islamic faith, Saturna Capital engages Amanie Advisors Sdn Bhd, a leading consultant specializing in Islamic finance.
