2000 and Before: Some Saudi 9/11 Hijackers Moderately Religious in Saudi Arabia

Although at least two of the 9/11 hijackers are distinctly unreligious when young (see (1998)), some of them appear to be moderately religious before they travel to Afghanistan:
According to the 9/11 Commission, Hamza and Ahmed Alghamdi attend prayer services regularly;
Salem Alhazmi stops drinking and starts going to the mosque three months before he disappears;
Abdulaziz Alomari and Ahmed Alnami are reported to become more religious after contact with the education system in Saudi Arabia (see 1999-2000).
But in general, the Saudi 9/11 hijackers are seen as devout, but not fanatical. For example, the 9/11 Commission will comment, “Their families often did not consider these young men religious zealots,” and Alnami’s father will say his son “practiced religion like most of us do.” [ABC News, 3/15/2002; 9/11 Commission, 7/24/2004, pp. 232-3]
