U.S. Army Major Nidal Hasan declared himself a "soldier of Allah" on business cards found in his apartment after the massacre at Fort Hood in which he stands accused of murdering 13 people.
The cards reveal more of his views of Islam.
On the cards, reportedly obtained over the Internet, Hasan included the acronyms "SoA" AND "SWT" beneath his name.
SoA stands for Soldier of Allah -- it's commonly used on jihadist Web sites. SWT is used by Muslims meaning "Glory to God."
One FBI agent told ABC News it's another piece of evidence investigators might have found if they had taken a closer look at Hasan.
