The biggest reason why Muslims now a days are being oppressed throughout the world. Because we have left all our history,our Islamic teachings, Love for our great HOLY PROPHET MUHAMMAD SAWand our moral values very far.
Nationalism is also a problem.Muslims from wherever he belongs is a Muslim and he is our brother and from Hadith MUSLIMS ARE LIKE A BODY, If one part feels the pain the whole body will.Islam teaches us to stop cruelity and always become a hope for Oppressed people and This will only be possible when we again become A Momin from our hearts.
The slave nations always hope for miracles and other things like this.
Miracles are only done by Allah on a nation when that certain nation proves itself by hardwork.
Now we have left the teachings of Islam .
But it's not late, there is time,we can achieve our goals which is the whole world.By whom we will be afraid in this world except Allah.The great empires are made by Iman and hardwork.So in a nut shell,
1. Iman
2. Piety deeds
