The Islamic community throughout the world faces challenges which are increasing daily and taking various shapes. They can be economic blockade, an intervention into the theology of Muslims, and many other problems, which can take very long to discus. What is the purpose of this struggle against Islam? It is to take Muslim’s confession from them by weakening the muslim community, influencing the ideology of Muslims and separating Muslims from the values of Islam. The question is how to resist this struggle? How can Muslims stand up against the world's aggression? Which takes different forms? What should we do in this situation? There is only one way out of Muslims to regain their former unity. Only when Muslims are united and become a united group, they will manage to stand up anyone and anything. All the Muslims are one third of the world total population. This is a very huge number! If Muslims Don't unite, no other methods, offered by scholars and Islamic movements, will help to resist world aggression.
