I believe they will lie regarding any matter, not just over religious ones, especially since their "faith" is one that is a bastardization of Judaism, Christianity and tribal practices tossed to allow familiarity with the indigenous peoples. What in their faith is "truth" that isn't recognized in it's borrowed sources?
Regarding the smoker, no such luck; Westerners should never feel at ease nor be interested in dealing with members of a culture/society that historically is hell bent on subjugating any and all who aren't "one" with them. The Islamic conditions for tolerance is to feign cooperation until they're in a position of strength, and then to proceed with enforcing second class citizenship to those that don't convert, or death. So much for a religion of peace, or whatever nonsensical, misleading title is applied as a deceptive practice to promote tolerance on their part. If the West, at this point in history, wasn't so dependent on Mideast oil, well, the Mideast would remain in the 7th century and no one would give a damn, however current economics changes that situation for the time being, doesn't it?
The 7th Century was far more progressive than modern Iran.
