They should unify their ranks to be able to resist this occupation. Praise be to God. Only God provides sustenance. Muslims believe that a lifetime is pre-determined and nobody can change it or push it forward or backward. Sustenance is also pre-determined.
Nothing can increase it or decrease it.
Sustenance is ordained when a person is still in the womb. Man should seek sustenance only from God, Praise and Glory be to him, and God has ordered us to ask him for our sustenance. Look at Bangladesh for example. It is classified as one of the poorest countries in the world, and Osama bin Laden doesn't live there. It is only God who provides food against hunger and security against fear.
