The main important principles or fundamentals of Islam religion are considered in the following:

1. Monotheism: Islam, as its name means, is peace and the call for full submission to God, the one and only one, with no partner, no son, no father, no companion, no resemblance. This full submission to God leads to peace in yourself and between yourself and the universe that you are part of it.
2. Muhammad prophethood: Prophet Muhammad is God messenger and prophet to call for Islam.
3. Quran holy book: Quran, Islam holy book, was revealed by God to Prophet Muhammad through the Angel Gabriel. Quran is the text of God holy words that remained without single letter alteration or addition since Quran revelation to prophet Muhammad (peace be upon him) until present and will remain as such until (with God promise) the Day of Judgment. See related question, below, on why Quran was revealed.
4. Sunnah: Prophet Muhammad sayings, doings, and practices that are recorded and authenticated by sincere early Muslims and followed up by Muslims.
5. Islam five pillars: These five pillars to be believed and followed up in by all Muslims. Denying any of them intentionally and knowingly by any Muslim gets him/her out of Islam faith. See related question, below, on Islam faith pillars.These five pillars are: 1) witness that no god except the one and only one God (Allah) and Muhammad is his messenger and prophet, 2) performing praying (Salat), 3) pay the alms giving (Zakat), 4) fasting Ramadan (Sawm), 5) and doing pilgrimage (Hajj) by who can afford it.

   • God prophets (including Noah, Abraham, Moses, Jesus, and Muhammad; peace upon them)
   • day of Judgment

8. Good deeds: Muslim is not only commanded to perform ritual worships but also, and equally important, to do good deeds for the benefit of oneself, family, community, and humanity.See related question, below, on Islam major teachings.
9. No religion compulsion: You are created free and you have full choice to believe in the religion and principles that you find them correct. Only God, the Creator and the All-Knowing, will judge your choice on the day of Judgment then, in the other eternal life, you go either to Hell or to the Paradise (with God mercy).See related question, below, on Quran Golden rules.

Yes, Muslims can eat beef, provided that it is slaughtered according to Halal practices (Dhabiha).
Per Isalm religion teachings, Muslims can eat beef.

Halal ,

Islam has laws regarding which foods can and cannot be eaten and also on the proper method of slaughtering an animal for consumption, known as dhabiĥa.

Explicitly forbidden substances

A variety of substances are considered as harmful (haraam) for humans to consume and, therefore, forbidden as per various Quranic verses:

• Pork meat (i.e. flesh of swine)[Qur'an 2:173]
• Blood[Qur'an 2:173]
• Animals slaughtered in the name of anyone but Allah (God). There are debates regarding the permissibility of meat slaughtered by Jews (i.e., kosher meat).[Qur'an 2:173]
• Carrion[Qur'an 5:3]
• "Fanged beasts of prey" as per the Sunnah, usually simplified to all carnivorous animals, with the exception of most fish and sea animals
• The meat of donkeys.
• All insects except for the locust (no reference)
• Alcohol and other intoxicants

There is some disagreement among Muslims regarding seafood, especially predatory sea creatures. IFANCA (Islamic Food and Nutrition Council of America) states, regarding the opinion of Islamic scholars:

• All are in agreement that fish with scales are halal.
• Sunnis consider all fish to be halal, while some Shias consider only shrimp and fish with scales to be halal.
• Within the Hanafi school of thought, the stronger position is that shellfish (shrimp, lobster, crab, clams, etc.) are prohibited]. But in the other three schools (Malaki, Shafi, Hanbali) crab and lobster are permissible.

Dhabiha: Method of slaughter

Dhabiha is the prescribed method of ritual slaughter of all animals excluding fish and most sea-life per Islamic law. This method of slaughtering animals consists of a swift, deep incision with a sharp knife on the neck, cutting the jugular veins and carotid arteries of both sides but leaving the spinal cord intact.

Kosher and Halal

There is a great deal of similarity between the laws of Dhabiĥa halal and kashrut, and there are also various differences. Whether or not Muslims can use kashrut standards as a replacement for halal standards is an ongoing debate, and the answer depends largely on the individual being asked. While some Muslim halal authorities accept kosher meat as halal, none of the Jewish kosher authorities accept meat certified as halal as kosher due to different
