Islamic centralism is characteristic of traditional Islam in general, whether in interpretations of the sacred text, among fundamentalists, or innovators. As reviewed before, Islam has always been a call that rejects all other faiths in favor of God’s sovereignty, considering itself the final Truth, the absolute standard, and its community the best one. Its scholars were more daring in the era of power and control, and were able to confront opposing ideas, using the tools of Greek philosophy without embarrassment. So, they produced a huge amount of jurisprudential rules. However, in the era of decline, the door to ijtihad was closed, and the centralist tendency was constantly exacerbated, until the world of Islam began to suffer from a pathological state of paranoia, fear of the disbelievers, and a feeling of inferiority.
