The Quran

حُرِّمَت عَلَيكُمُ المَيتَةُ وَالدَّمُ وَلَحمُ الخِنزيرِ وَما أُهِلَّ لِغَيرِ اللَّهِ بِهِ وَالمُنخَنِقَةُ وَالمَوقوذَةُ وَالمُتَرَدِّيَةُ وَالنَّطيحَةُ وَما أَكَلَ السَّبُعُ إِلّا ما ذَكَّيتُم وَما ذُبِحَ عَلَى النُّصُبِ وَأَن تَستَقسِموا بِالأَزلامِ ۚ ذٰلِكُم فِسقٌ ۗ اليَومَ يَئِسَ الَّذينَ كَفَروا مِن دينِكُم فَلا تَخشَوهُم وَاخشَونِ ۚ اليَومَ أَكمَلتُ لَكُم دينَكُم وَأَتمَمتُ عَلَيكُم نِعمَتي وَرَضيتُ لَكُمُ الإِسلامَ دينًا ۚ فَمَنِ اضطُرَّ في مَخمَصَةٍ غَيرَ مُتَجانِفٍ لِإِثمٍ ۙ فَإِنَّ اللَّهَ غَفورٌ رَحيمٌ

Mir Aneesuddin

Forbidden to you as food¹ are :- that which dies of itself and blood and flesh of swine and that on which any other name than that of Allah has been invoked and that killed by strangling and that beaten to death and that killed by a fall and that killed by being smitten by a horn and that which wild beasts have eaten except that you purify it (by properly slaughtering it in Islamic manner, while it is still alive) and that which is sacrificed on stones (before and for idols) and that you seek division with arrows (is also forbidden), that is transgression. “This day, those who do not believe have lost hope, (due to the success) of your religion, therefore do not fear them but fear Me. This day I have perfected your religion for you and completed My favour on you and I have chosen ‘Al Islam’ as the religion for you².” But (if) anyone is compelled by hunger (to eat something for that which is forbidden) without inclining towards sin, then Allah is Protectively Forgiving, Merciful.

Prohibited Food and Intoxicants: Food that is prohibited is harmful for the human body.
Pork: Trichinosis is commonly caused by the ingestion of improperly handled fresh pork that has been infested with Trichinella Spirales, a genus of a nematode which very often infects swine. In the early stages of the disease, the symptoms are loss of appetite, nausea, vomiting, periodic pains in the abdomen and diarrhea. This is followed by muscle soreness and sometimes very severe muscular pain. The disease may last for several weeks during which time there may be moderate to high fever, sometimes as high as 104° F - 105° F. A fairly high percentage of swine may be infected with Trichina. Tarmia Solium, pork tape worm also causes illness when infected. (Food and Food Products Vol.1 M.B. Jacobs, Inter Science Publishers Inc. New York 1951, p.445.)
Flesh of Dead Animals: Early man sometimes became ill or died after eating the flesh of dead animals (Encyclopaedia Britanica 1981 Vol.5 P.864).
Blood as a Source of Disease: The Streptococcus Viridans organisms are found in the throats of 90 percent healthy persons. The same organism cultured from the blood strains is highly pathogenic and usually indicates the presence of the disease subacute bacteria) endocarditis (chronic bacterial invasion of the lining of the heart). Exotoxin that is produced by Corynebacterum diphlheriae which causes diphtheria, released into the surrounding tissues is absorbed into the blood stream from the local infection within the throat. Endotoxic infection typhoid: The organism creates a local infection within the intestinal tract and then spreads rapidly through the lymphatic system into the blood. Tuberculosis: if the infection spreads into the blood stream, seeding of any organ or tissue of the body may occur. The mechanism of transfer of agents of diseases to the blood is applicable to animals loo: Examination of blood cells of cattle may reveal abnormal lymphocytic cells characteristic of leukemia. Low number of leucocytes in blood indicates the presence of viral diseases such as hog cholera and infectious hepatitis in dogs. Neutrophil levels in blood increase in chronic bacterial diseases, such as canine pneumonia and uterine infection in female animals. Elevated monocyte levels in blood occur in chronic granulomatous diseases e.g. histoplasmosis and tuberculosis. Canine parasitism and allergic skin disorders are characterized by elevated eosinophil levels in blood (Encyclopaedia Britanica 1981. Vol.5 P 855 - 873). In view of the above facts blood is harmful as food. Incomplete bleeding (during slaughter) encourages the spread of bacteria, the better and more sanitary the bleeding, the better will be the keeping quality of meat. (Food Microbiology by W.C. Frazier P. 266 Tata Me Grawhill Publishing Co. Ltd. N.Delhi 1967) It is probably due to this reason that in the Islamic way of slaughtering an animal for food, it is made to die due to excessive bleeding; which also minimizes many Other agents of diseases.
This statement is considered to be the last revelation.
