I know these folks pray a lot, but is it fair to ask them specifically what they are praying for?
I mean, if they are praying for my violent end, that certainly takes the 'shine' off of the dutiful prayers.
It is all excessive legalism, and they are a prisoner to it.
The 5 pillars of Islam dictate these legalistic Obsessive Compulsive Disorder-like rituals (pray 5 times a day, pilgrimage to Mecca, fasting, etc).
The "Sixth" pillar of Islam is Jihad, which is kind of a "Magic Bullet" ticket to heaven on the Expressway with E-Z Pass, or so they think.
None of this, of course, gets them into heaven or makes them right with God.
