Quran & Hadith: Blood

BLOOD in the Quran

حرمت عليكم الميتة والدم ولحم الخنزير ومااهل لغير الله به والمنخنقة والموقوذة والمتردية والنطيحة ومااكل السبع الا ماذكيتم وماذبح على النصب وان تستقسموا بالازلام ذلك فسق اليوم يئس الذين كفروا من دينكم فلا تخشوهم واخشون اليوم اكملت لكم دينكم واتممت عليكم نعمتي ورضيت لكم الاسلام دينا فمن اضطر في مخمصة غير متجانف لاثم فان الله غفور رحيم

"Forbidden to you (for food) are: carrion, blood, the flesh of swine, and that on which hath been invoked the name of other than Allah; that which hath been killed by strangling, or by a violent blow, or by a headlong fall, or by being gored to death; that which hath been (partly) eaten by a wild animal; unless ye are able to slaughter it (in due form); that which is sacrificed on stone (altars); (forbidden) also is the division (of meat) by raffling with arrows: that is impiety. This day have those who reject faith given up all hope of your religion: yet fear them not but fear Me. This day have I perfected your religion for you, completed My favour upon you, and have chosen for you Islam as your religion. But if any is forced by hunger, with no inclination to transgression, Allah is indeed Oft-forgiving, Most Merciful."
— Quran, Surat Al-Ma'idah 5:3

Hadith referencing BLOOD

Narrated by Muhammad bin Idris Ash-Shafi`i :

Ibn `Umar said that the Messenger of Allah said, “We were allowed two dead animals and two (kinds of) blood. As for the two dead animals, they are fish and locust. As for the two bloods, they are liver and spleen.”

Imam Ahmad bin Hanbal, Ibn Majah, Ad-Daraqutni and Al-Bayhaqi also recorded this hadith.

Islamic Schools of Thought

There are no differences between the methahab with regards to the consumption of blood.

"People of the Pre-Islamic Period of Ignorance (Al-Jahiliyyah) used to put [blood] in the entrails, grill it and eat it. However, whatever blood remaining inside the flesh of the slaughtered animal or in the veins is lawful. Rather, it is ot considred impure even if one touches it with the hand or with a piece of cotton for example and it leaves visible traces."
— Al Fawzan, Dr. Salih (Professor of Islamic Jurisprudence. Member, The Permanent Committee on Fatwa and Research). "A Summary of Islamic Jurisprudence, Vol. 2," Section XI: Food, Chapter 1, p. 652.

In this respect, Sheikh al-Islam Ibn Taymiyah said:
"The right opinion is that the blood that is forbidden is the shed, the spilled or the poured blood; however, the blood left in the veins is not deemed prohibited by any of Muslim scholars."
