Q. Can you rely on a non-Jewish tailor, when he assures that there is no linen in the wool suits he makes for you, specially when you have been his client for many years and he is afraid to loose a customer?
How about, if you and others have checked a number of suits and no shaatnez was found?
A. Re- question 2559 above. Poskim disagree as to the extent you may trust a Gentiles testimony in Rabbinic prohibitions under certain circumstances. (See Maharam Shick Y.D. 295). Horav Shlomo Miller’s Shlit’a opinion is that if you have already tested at least three suits manufactured by this tailor for you or others, and no shatnez was found. And you tell him that you may be checking this suit also, you may rely in his word, since if caught he will loose his customers. It is still preferable to have it checked if possible. (See next question).
