al-Taqiyya...

The concept of 'al-Taqiyya' is to be considered. I do not know as absolute fact, but it is my suspicion that this concept is invoked with regularity among the muslim ranks.

You do hear this from muslim leaders. When they speak to Western audiences they say things that we may want to hear, and then when speaking to their muslim brothers, the truth comes out and it is quite different than what was spoken to the Western audience.

The word "al-Taqiyya" literally means: "Concealing or disguising one's beliefs, convictions, ideas, feelings, opinions, and/or strategies at a time of eminent danger, whether now or later in time, to save oneself from physical and/or mental injury." A one-word translation would be"Dissimulation."

Ibn Abbas also commented on the above verse, as narrated in Sunan al-Bayhaqi and Mustadrak al-Hakim, by saying: "al-Taqiyya is the uttering of the tongue, while the heart is comfortable with faith." NOTE: The meaning is that the tongue is permitted to utter anything in a time of need, as long as the heart is not affected; and one is still comfortable with faith.

Unless proven absolutely wrong, I would again say, this a normal practice among many muslims when addressing the 'infidels' ...
