According to Sheikh Youssef Al-Qaradawi, there are three kinds of kufr [unbelief]. There is atheism [elhad], which is a total denial of the existence of the Almighty God. There is polytheism [shirk], which means believing in more than one god. The third kind is the denial of Islam and the message brought by the Prophet Mohammed. Westerners are kuffar because they do not believe in Islam.
