Is it permissible for a Muslim to buy halal meat from a place that sells haram meat, provided that each type is stored and packaged separately? And is it permissible to buy halal foods from a store that sells alcoholic beverages in a dedicated section, if the owner of the store is not Muslim?

A Muslim is not permitted to assist anyone in sin or transgression. Therefore, if someone who sells only permissible (halal) items is available, one must deal with them exclusively. However, if the only available vendor sells both permissible and impermissible (haram) items, a Muslim is allowed to purchase the permissible and lawful foods from them, provided these items are not mixed with impermissible ones. This is in accordance with Allah's saying: "So fear Allah as much as you are able."
