Everything will be haraam and unfavorable if obtained in a way that is less healthy and eaten excessively. Allah forbid something there must be evil in it, if Allah justifies something there must be good in it for the survival of human life on this earth. Thus some hadiths in the Qur'an forbid certain animals to eat humans.
Forbidden to you (eat) carrion, blood, pork, (animal flesh) slaughtered on behalf of other than Allah, the choked, the smitten, the fallen, the headless, and the beaten by the beasts, except those which you slaughtered, and (forbidden for you) slaughtered for idols. And (forbidden also) to draw fate with arrows, (to draw fate with the arrow) is wickedness. On this day the unbelievers have been desperate to (defeat) your religion, therefore fear not them and fear me. On the day I have perfected for you your religion, and I have Enhanced you My favor, and I have accepted Islam to be a religion for you. So whoever is forced to go hungry without sin, Allah is Forgiving, Most Wanting. "(Surah Al-Maidah (5): 3)
- Pig
Many scientists have discovered that pig DNA is the same as human DNA, pig's heart is used to replace some parts of the human heart that no longer work. This shows that many vital system similarities occur in humans and pigs. The internal structure and pig skin are very similar to humans. And this is one of the reasons why pigs are often used as a substitute for human anatomy in surgical practice of medical students.
Pigs are the reservoir of disease.
Some seeds of pig-carrying diseases such as ribbon worms (Taenia solium), spiral worms (Trichinella spiralis), mining worms (Ancylostoma duodenale), Pulmonary worms (Paragonimus pulmonaris), Intestinal worms (Fasciolopsis buski), Schistosoma worms (japonicum), Tuberculosis (TB) Cholera bacteria (Salmonella choleraesuis), Bacteria Brucellosis suis, Smallpox virus, Scabies Virus, Parasite protozoa Balantidium coli, Parasite protozoa Toxoplasma gondii
The bad nature of pigs
The stupid, lazy, faggy pigs of all animals even though their stomachs are full, eating any kind of feces, including their own manure and dung. Sometimes he pissed on his shit and ate it if it was in front of him, then ate it again. Pigs are the only mammals that eat the soil, eat it in large quantities and in a long time if left alone. The skin of the person who eats the pigs will emit the odor away.
Another study revealed that humans and animals that consume pork, gradually have a connective tissue rich in pork fat. In other words, the pork-eaters outwardly behave similarly to the animals they eat, as the saying goes "You Are What You Eat". That is why Islam forbids and forbids pork eaten by humans.
2, Dog
Islam forbids the meat of dogs eaten by humans. Rasulullah Saw said:
"Any beast that has a canine is haram to eat." (Muslim)
Dogs are one of the beasts & have canine teeth, feed on fellow animals and blood. Blood contains a lot of dirt, bacteria, and diseases because the blood is the place of transport of body substances. In addition, every time you hear the call to prayer, Dogs always howling long & that voice can even make anak2 baby crying, that is signify the voices of devil out when adzan dikumandangkan. dogs are so sensitive to the presence of demons.
Scientific Facts Dogs Endanger Human Health
Scientifically, dogs can transmit a variety of dangerous diseases. Dogs do not sweat. Dogs do not have sweat cells all over his body. to cool his body, the dog stuck out his tongue and drained the saliva. It is feared that the saliva contains bacteria that can be harmful. Because, there are caterpillars that grow in their gut. The caterpillar takes out the eggs together with the release of dog poop. When the dog licks his butt, the caterpillar eggs will move on to it. Then from the lick of this dog, the caterpillar eggs will move on the containers, plates, and hands of the owners, The liquids that come out of it in the form of dirt, urine, and so forth, can transmit a virus called "tocks characins". This virus can lead to blurred vision and blindness in humans.
Islam requires removing the dogs unclean with the soil.
Scientists are trying to explore the knowledge of why Islam requires humans to remove or wash the dogs unclean by using the soil. Scientific facts, the doctors put forward the reason, because virus-causing disease will reach its peak in small size. The smaller the shape, the virus will be more dangerous, because the potential to stick and attached to the container wall is growing.
Washing with soil is stronger in the sterilization process than washing with water. Because, the strength of the soil in stopping the dog's saliva reaction and the viruses contained in it, is greater than by splashing water or using the hands while cleaning the walls of the former dog lick container. That's because there is a difference in compressive strength in the region between the cainan (dog saliva) and the soil. This can be likened to Physics like putting chalk on the ink.
Conclusion there are many other animals that are forbidden to be eaten by humans, not just animals but also halal can be prohibited if too excessive that will give bad effect into the body. Islam requires eating good good. Islam forbids consuming both in terms of nature and from its unfavorable dzat or anything kosher but consumed excessively or how to get it in a way that is not commendable that harm others.source..
