Each of these words describes a different style of deception used by Muslims when discussing Islam or their activities as Muslims.
Mohammed famously said, “War is deceit.” (Sahih Bukhari, Vol. 4, Book 52, Nr.268). The Quran boasts that Allah is the “master of all scheming” (Quran 13:42) and that he is “profound in his machinations” (Quran 8:30). Western civilizations are not accustomed to dealing with people, who have developed deception into an art form. Knowledge is power, and the best way to combat the Islamist agenda is to say, “We are used to your lying. Knock it off!”
Taqiyya is defined as dissimulation about ones Muslim identity. It comes from the verse in the Quran that says, “Let believers not make friends with infidels in preference to the faithful – he that does has nothing to hope for from Allah – except in self-defense (illaan tattaqoo minhum tuqatan (Quran 3:28).
This “self-defense” justifies dissimulation.Islamic Sharia Law provides, “When it is possible to achieve an aim by lying but not by telling the truth, it is permissible to lie if attaining the goal is permissible, and lying is obligatory if the goal is obligatory.”
Reliance of the Traveller. Section r8.2 PERMISSIBLE LYING. The Prophet said: “He who settles disagreements between people to bring about good or says something commendable is not a liar”). Examples include lying to protect Islam or a Muslim.
Tawriya is defined as concealing, and it could be called “creative lying” or where appropriate “lying under oath”. It is OK to break the intent of the oath, as long as you don’t break the letter of the oath.
Reliance of the Traveller. Section o19.1 If one swears “I will not eat this wheat,” but then makes it into flour or bread (and eats it), one has not broken one’s oath.
Reliance of the Traveller. Section o19.5 When a person swearing an oath about something (in the future, affirming or denying that it will occur) includes the expression “in sha’ Allah (“if Allah will”), before finishing the oath, then the oath is not broken in any event if he thereby intends to provide for exceptions.
How does this work? Suppose someone protests that Surah 1 of the Quran demeans Christians and Jews, because it is a supplication Muslims make to Allah seventeen times a day to keep them from the path of“those with whom God is angry” and “those who have lost their way”.
A Muslim might respond, “Surah 1 never mentions Jews or Christians.” He is practicing tawriya, because while Surah 1 does not mention Jews and Christians by name, but he knows full-well that the words “those” refer to Jews and Christians.
Another example would be when a Muslim responds to your greeting of “Merry Christmas!” He might say, “I wish you the best.” In your mind,you think he has returned a Christmas greeting. In actuality, he has expressed his wish for you to convert to Islam; he wishes the best for you which, in his view, is becoming a Muslim.
