Is it permissible to buy meat thinking that it is slaughtered according to Islamic laws from a super-market owned by a Muslim who [also] sells alcoholic drinks?
Answer
Yes, it is permissible; and it is halal to eat, even if it previously came from a non-Muslim as long as there is a likelihood that the shopkeeper has ascertained that it was slaughtered according to the shari‘a laws; but not if there is no such likelihood.
