National Review columnist Rich Lowry came close but missed the main point in the primary motive of the Islamic terrorists. The main motive is in the Qur’an. Sura 2.29 says,
“Fight those who believe not In
God nor the Last day,
Nor hold that forbidden
Which hath been forbidden
By God and His Apostle,
Nor acknowledge the Religion
Of Truth, (even if they are)
Of the people of the Book,
Until they pay the Jizya
With willing submission,
And Feel themselves subdued.”
(From the translation by Abdullah Yusuf Ali)
The book is the Bible and people of the Book are Christians and Jews. The Jizya was a special tax that was imposed on non-Muslims in some Islamic states. I don’t know if any Islamic states impose it today.
Islamic terrorists follow orthodox Islam, meaning they accept literally everything in the Qur’an. Sura 9:29 was the last verse revealed to Muhammad shortly before he died, except for Sura 110. According to the doctrine of abrogation, Sura 9:29 abrogates or nullifies any contradicting verses revealed before that.
It is important to note that some Muslims follow heterodox Islam. That means they do not follow all the Islamic doctrines.
They may not follow all of the Qur’an or may interpret passages differently. An example is the Sufis who are more mystical in their beliefs “based on peace, tolerance, interreligious cooperation, respect and love.” (Quoted from an article about Shiehk Kabbini in Wikipedia.)
It is also important to note that experts on Islam in the United States such as Shiekh Hisham Kabbini say that about 80 percent of the mosques in the United States teach orthodox Islam. However, Shiekh Kabbini also says that many who hear the orthodox Islamic teachings do not agree with it.
