Thanks for the A2A, but….
What??? WHAAAAAT????
Either you have no understanding about what the narcissistic personality disorder is about or you have no understanding of Islam or religion in general. Now as for some of the radical leaders in contemporary Islam, I think you could make a case for that. There certainly are many who exhibit some pretty extreme behavior patterns consistent with narcissism and its handmaidens, paranoia, delusions of grandeur and obsessive/compulsive disorder. That at very best is a twisting of the religious precepts to serve their own agenda.
The thing about religion is that it tends to be the very opposite of narcissistic. It is about the “other", not about the self. Look at the five pillars of Islam: Faith, Prayer, Charity, Fasting and Pilgrimage to Mecca. They are all about getting past ones self, even self denial, and moving into closer relationship with Allah (God) and being a conduit of God’s blessing to the world. Narcissism is extreme self centeredness. Islam is extreme ‘other’ centeredness. Polar opposites.
Some researchers have discussed the correlation of healthy narcissism and industrial progress, so a lack of industrial revolution in Middle East is a sign of high self-annihilation. But Hadith teaches: wa linafsika alayka haqqun: Your biological and physical self has rights too. So, Islam has has a buffer to extreme Buddhist self denial which secular Buddhism seeks to cure which is already cured within sacred texts of Islam.
