However, if the Muslim who slaughtered it remains in the presence of the non-Muslim all the time until all the meat is sold, it will be permissible to consume such meat. Alternatively, the person who slaughtered the meat could call another Muslim to keep watch over it until all the meat is sold. At no time should any Muslim absent himself from that meat.
