Permissibility of mixing pork fat in food
What is the ruling on eating, drinking, or adding pork fat to food?
It is prohibited to eat, drink, or add por fat to food. Jaber Ibn Abdullah (may God be pleased with him) narrated that the Messenger of God (peace and blessings be upon him) said in the year of the conquest of Mecca, “Verily God the High and Mighty and His Messenger have prohibited the sale of alcohol, carrion, pigs, and idols.” Upon this, he was asked, “O Messenger of God! What about the fat of dead animals? It is used to caulk boats, grease hides, and people use it to light lamps.” The Messenger of God said, ‘No. it is prohibited.”
According to al-Qurtubi, the prohibition of pork established by the Quranic verse, “He has only forbidden you carrion, blood, pig’s meat, and animals over which any name other than God’s has been invoked. But if anyone is forced to eat such things by hunger, rather than desire or excess, he commits no sin: God is most merciful and forgiving” (Quran 2: 173), extends to their fat, cartilage, and every part of them, even if they are slaughtered.
Al-Qurtubi explains that there is a community consensus on the prohibition of pork fat. In their substantiation of this, Malik and his disciples maintained that a person who swears that he will not eat fat, and eats meat does not break his oath by eating meat. On the other hand, if he makes an oath not to eat meat but eats fat, he breaks his oath. The reason for this is because meat with fat tissue is still called meat; fat is included in the designation of meat but not vice versa and God Almighty has prohibited the meat of pigs. The reference to meat also includes a reference to fat because fat is included under the designation of meat.
And God Almighty knows best.
