Nasir Abas was a leader of Indonesia's Jamaah Islamiyyah but left the group when it began to attacking civilians like al-Qa'ida has done.  He has since written a book and conducted numerous interviews about his disgust over violence against civilians in the name of religion.

The following are his quotes during a 2005 interview:




"Our job is just to protect our belief in Islam, to protect the Muslims, to protect our homeland. That is jihad. But if you -- if we are -- if jihad is meaning to kill the civilians, non-Muslim, that is not jihad."


"...because what I'm teaching is just use for in battlefield, to use for defending their homeland." 




"I feel upset when I heard some of my friends, some of my students, some of my relatives, you know, like Ali Grufanis, he is my brother-in-law. He is involved in the Bali bombs of October. So I feel upset, yeah. I think that this is the wrong way they have chosen. They misused the knowledge." 




"...this is a chance and the time for me to explain to the people, you know, that the ideology is wrong."



"We explain to them that the ideology is deviant, it's deviation of Islam, a misunderstanding, misinterpretation about -- Islam is about holy Koran."
