do not eat the flesh of an animal which has been slaughtered without a mention of the name of god it is a sinful deed. satan teaches his friends to argue with you. if you obey them you will certainly be idol worshippers.
ولا تأكلوا مما لم يذكر اسم الله عليه وإنه لفسق وإن الشياطين ليوحون إلى أوليائهم ليجادلوكم وإن أطعتموهم إنكم لمشركون
