I'll tell you a fine story.. Once.. The pharaohs were the greatest nation on Earth, they ruled, were magnificent in science, chemistry, and many many sciences... The Pyramids, Sphinx, Mummifications are a great witness...
The Pharaohs started to disbelieve in God, let me tell you that ancient Egypt used to believe in one Almighty God Called "Amun"... When they abandoned that, started to be Tyrants and abuse the weak, God Sent the ROMAN CHRISTIAN EMPIRE.. An Empire that belived in one God.. treated people well, and abolished slavery.
After a while, the Roman Empire got crazy, burnt Christians, enforced slavery, and the people suffered great agony and distress.. That was when Muslims came.. People with the word of God, love each other, abolished slavery, and the like, The Roman Empire was destroyed by Omar ibn Al Khattab, and Muslims Ruled. Peace Love and Happiness...
But Suddenly, many Muslims changed...
Terrorism, Slavery, bad actions, Maltreatment for women, hate and racism, so the circle began to move again.. It is endless...
