Is there an explicit verse that prohibits eating unslaughtered meat? And is it permissible to eat unslaughtered meat when a person cannot find what they desire of food?

Meat that has not been ritually slaughtered is considered carrion (maytah), and it has been forbidden in the Holy Qur'an in several places, such as His (Allah's) saying: "{Forbidden to you are carrion}" and His saying: "{Say, 'I do not find in what has been revealed to me anything forbidden to a consumer who eats it, except that it be carrion'}." Carrion is permissible only in cases of necessity. Necessity is not defined by the absence of food that a person desires, but rather by circumstances where one fears falling into perdition or unbearable hardship. The default ruling for meat is prohibition unless it has been ritually slaughtered according to Islamic law. Whatever is not ritually slaughtered is considered carrion, which is not permissible except in cases of necessity, as explicitly stated in the Qur'an.
