Islamic law unambiguously splits the world into two perpetually warring halves—the Islamic world versus the non-Islamic—and holds it to be God’s will for the former to subsume the latter. Yet if war with the infidel is a perpetual affair, if war is deceit, and if deeds are justified by intentions—any number of Muslims will naturally conclude that they have a divinely sanctioned right to deceive, so long as they believe their deception serves to aid Islam “until all chaos ceases, and all religion belongs to God.” Such deception will further be seen as a means to an altruistic end. Muslim overtures for peace, dialogue, or even temporary truces must be seen in this light, evoking the practical observations of philosopher James Lorimer, uttered over a century ago: “So long as Islam endures, the reconciliation of its adherents, even with Jews and Christians, and still more with the rest of mankind, must continue to be an insoluble problem.”
The above is a quote from an excellent article by Raymond Ibrahim on taqiyya. Read the whole article here: How Taqiyya Alters Islam’s Rules of War.
