The Koran is said to be dictated word-for-word by Allah himself, from the angel Gabriel to the prophet Muhammad. Therefore, every word of the Koran is the word of God himself and every word is valid for all of time and cannot be questioned, changed, or reformed. This means that all “peaceful” Muslims have to reject Koranic literalism, but to do so means they do not accept the exact words of Allah. According to the Koran, this places peaceful Muslims in the same category as jewish people and Christians; they “must abide in the fire of hell. They are the worst of creatures.” (Koran, Surah 98:6).
One of the goals of Muslims who follow Islam is to expand and spread the practice of Islam to all over the earth. While conversion to Islam is never supposed to be forced through torture, it can be pressured by coercion. Those who still refuse to convert to Islam can be severely punished or even killed (Vol 4, Bk 53, Hadith 392).
One of the biggest obstacles to American efforts to understanding Islam can be attributed to the Islamic and Muslim principle of “religious deception”, in which Muslims are to deceive non-Muslims, toward the goal of advancing the cause of Islam. Today, Muslim groups employ tactics of deception and omission to give the impression that “Islam is a religion of peace”. The prophet said, “War is deceit.” (Vol 4, Bk 52, Hadith 269)
Lying, generally speaking, is not allowed in Islam. However, there are situations where it is acceptable and even encouraged. This concept, called Taqiyya, is a form of deception used to deceive an enemy (any non-Muslim). So, a Muslim is allowed to lie to prevent harm or protect themselves or Islam. (Koran, Surah 3:28)
In Muslim thinking, the world is divided into competing sides. The dar al-Islam (House of Islam) where Islamic law dominates, and dar al-harb (House of War) which is the rest of the world that Islam does not control, is how the world is viewed according to the Hadith. (Vol 4, Bk 52, Hadith 196) It is prescribed for dar al-Islam to fight and destroy dar al-harb and permanently incorporate it. Muslims in Western nations are called by Islamic extremists to overthrow the secular governments in which they live, all in accordance with Allah's command.
