“Historically, examples of taqiyya include permission to renounce Islam itself in order to save one’s neck or ingratiate oneself with an enemy.
“Due to the state of war between dar al-Islam [those nations that have submitted to Islamic rule] and dar al-harb [those nations that have NOT submitted to Islamic rule], ruses of war, i.e., systematic lying to the infidel, must be considered part and parcel of Islamic tactics. The parroting by Muslim organizations throughout dar al-harb that “Islam is a religion of peace,” or that the origins of Muslim violence lie in the unbalanced psyches of particular individual “fanatics,” must be considered as disinformation intended to induce the infidel world to let down its guard.
Of course, individual Muslims may genuinely regard their religion as “peaceful” — but only insofar as they are ignorant of its true teachings, or in the sense of the Egyptian theorist Sayyid Qutb, who posited in his Islam and Universal Peace that true peace would prevail in the world just as soon as Islam had conquered it.
A telling point is that, while Muslims who present their religion as peaceful abound throughout dar al-harb, they are nearly non-existent in dar al-Islam. A Muslim apostate once suggested to me a litmus test for Westerners who believe that Islam is a religion of “peace” and “tolerance”: try making that point on a street corner in Ramallah, or Riyadh, or Islamabad, or anywhere in the Muslim world. He assured me you wouldn’t live five minutes.”
