Sheikh Salman al-Oadah
It is permissible to eat uncooked meat. The blood contained within it is from the blood that is overlooked by Islamic Law, since it is difficult to avoid. Moreover, the liver is basically blood and it is permitted by consensus.
What is prohibited is to drink pure blood on its own, since Allah says: “He has only forbidden you carrion, blood, the flesh of swine, and any food over which the name of other than Allah has been invoked…” [Sûrah al-Nahl: 115]
Allah has permitted us to eat the flesh of all land animals and birds except for what he specifically prohibited, such as fanged carnivores, taloned birds of prey, and unclean insects.
There is nothing mentioned in either the Qur’ân or the Sunnah that the flesh of those permitted animals must be cooked before it can be eaten. Not once has cooking been cited as a condition of permissibility for eating meat. This is in spite of the fact that the Prophet (peace be upon him) has commanded us to cook certain foods. He ordered us to cook garlic and onions in order to diminish their smell. [Sahîh Muslim (567)] However, he never said any such thing about meat.
This shows is that the permission to eat meat is general, unqualified by it being cooked or left uncooked.
However, we do not advise people to eat raw meat, since this can expose people to certain diseases like toxoplasmosis. This is especially true for certain kinds of meat like hamburger. For this reason, some Islamic jurists have issued a ruling that eating uncooked meat is disliked (makrûh). This opinion is expressed by Ibn Muflih in Adâb al-Sharî`ah.
In other legal works, like al-Insâf and al-Furû`, we see it stated: “There is no objection to eating meat that is uncooked.” This is the correct ruling, and Allah knows best.
