Dr. Mohammad bin Abdul Karim Al-Issa, Secretary General of the Muslim World League, said that coexistence is inevitable necessity for human beings, while the concept is not fully realized by humans around the world; leading to emergence of hatred phenomenon that created extremism and terrorism. In a conference for Muslim World League (MWL), in Durban city of South African, Dr. Al-Issa asked religious thinkers and scholars around world to fight phenomenon of hatred that caused many tragedies and was the main reason for wars in many other cases. He further added that, many people could not understand creator's purpose in creating diversity and pluralism, and stressed on the essentiality of redefining this point to be full absorbed by humans with the aim of reaching peace, cooperation, tolerance and love between us.
