Why do you think that Islam countries are underdeveloped? At the beginning, Islam countries were forwarding science but nowadays they stop developing and pretending to be ignorent. At the beginning Islam countries were supporting each other but nowadays they are treating as an enemy to each other. Is it because of Islam or is it because of people that are not obeying Islam? There is a good word that Cat Stewens said about Islam “I met quran before I met Muslims. If I met Muslims before Quran probably I won’t be a Muslim” Do not accuse Islam because of Islamic countries or muslims who are not obeying Quran, accuse them.
