1. If you want to fight then pick on someone you can beat. If you do this you will always win. But then you will be called a bully. That is alright.
2. The weak of today are the Muslims. And the Muslims are weak because they choose to be weak. I say they choose because Allah has not just given them a good religion, a religion of high values which when practiced would make them strong and respected but Allah has also given them resources of wealth which enable them to have a good life doing nothing. With money they can get others to do their work for them.
3. Because of all these the Muslims are weak and can be bullied by anyone. And when they get bullied no one, certainly not their Muslim brothers will come to their help. So whenever a bully wants to bully he will always pick on the Muslims.
