Islam is based upon the visions of the prophet Mohammad, who was told by the angel Jabreel (Gabriel): There was only one God, "Allah," who ruled the universe. Idolatry and the recognition of other gods was wickedness.Allah would bring judgment on the world; he would reward the righteous and punish the wicked. Allah had sent previous prophets, including Abraham, Moses, and Jesus, however their message was either imperfect or had been rejected by those who heard it. Muhammad was Allah’s last messenger who would bring the perfect message to humanity.
Among Islamic beliefs and culture: moral behavior. No alcohol, gambling, usury, cannot eat pork, sexual impropriety was strictly forbidden.
All persons are equal in the eyes of God. This is one reason why Pakistan, which is Islamic, often comes into conflict with India. India is predominantly Hindu, which stresses traditional inequality through the Caste system; although both were once part of the same country, the differences are severe.
A man is allowed to have up to four wives, but only if he can support them.
Jews and Christians are dhimmis, "people of the book," and therefore should be protected. (the Book being the Hebrew Scriptures).
All Muslims have the obligation of jihad; meaning "struggle," or "self exertion." It typically means a struggle against sin; but oftentimes has been translated to mean "holy war."
Devout Muslims follow the Five Pillars of Islam:
One should recite the Islamic Creed at least five times each day: "There is no God but God, and Mohammad is his messenger."
o One should pray five times each day; beginning at dawn, and at appointed times during the day. From the minarets of the Mosque, a call to prayer (a loud wailing chant) is the call to prayer, when all bow towards Mecca and pray.
o One has a duty to support the poor.
o During the holy month of Ramadan, one must fast during the daylight hours. One may eat only during nighttime hours.
o If possible, one should make at least one pilgrimage or hajj during his lifetime to Mecca.
Islamic culture is itself a contentious term. Muslims live in many different countries and communities, and it can be difficult to isolate points of cultural unity among Muslims, besides their adherence to the religion of Islam. Anthropologists and historians nevertheless study Islam as an aspect of, and influence on, culture in the regions where the religion is predominant.
The noted historian of Islam, Marshall Hodgson, noted the above difficulty of religious versus secular academic usage of the words "Islamic" and "Muslim" in his three-volume work, The Venture Of Islam. He proposed to resolve it by only using these terms for purely religious phenomena, and invented the term "Islamicate" to denote all cultural aspects of historically Muslim peoples. However, his distinction has not been widely adopted, and confusion remains in common usage of these articles.
Islamic culture generally includes all the practices which have developed around the religion of Islam, including Qur'anic ones such as prayer (salah) and non-Qur'anic such as divisions f the world in Islam
