With respect to slaughtering, if the meat is taken from a Muslim who claims that it was slaughtered according to the Sharia and one finds is probable that the Muslim is saying the truth, it is permissible to consume it. However, it is not permissible – based on compulsory precaution – to consume food that non-Muslims – except Christians, Jews and Zoroastrians – touched with dampness. If there is doubt, one could consider it to be tahir.
