When a dangerous situation, say a natural disaster like an earthquake occurs, do you know what the difference between a believer and a non-believer will be?
The non-believer will die crushed by the building he's in.
The believer will start praying and then die just like the non-believer.
If you need that feeling of being with someone and having a helping hand in a time of need, maybe you need more friends in your life?
It doesn't really matter whether a believer or an unbeliever is in the building. If you know the basic rules of behavior in an earthquake or fire, you can improve your chances of survival.
Prayer helps a person to calm down, concentrate and not panic, which is very important in a difficult situation.
