Monotheism, or belief in one God, is a belief. There are many monotheistic religious beliefs. There are many monotheistic religions, including Islam, Judaism and Zoroastrianism. Each one has its own beliefs and practices. Let's see the differences.
Islam
Islam is monotheistic religion that emphasizes God's oneness. Islam holds that God is the only creator and deserving of worship. This idea is stressed throughout the Qur'an. Most verses in Qur'an stress the Oneness and Oneness of Allah.
Christianity, Judaism, Islam are the major monotheistic religions. Abraham is the root of these traditions. Abraham, the father in Abrahamic religions and the founder of these traditions, was asked to give up his only son. God intervened to save him. He then offered Abraham to sacrifice a ram. In the Bible, the promise messiah is the focal point of Jewish people's hope.

According to Islam, worship is a very important part of Islam. Worship does not just include prayers and rituals. All of us should engage in worship to please God. These activities might include charity donations, seeking out knowledge, or being an agent of good in this world.
Judaism
Judaism belongs to the Abrahamic group of religions and is monotheistic. Its roots lie in the Bronze Age of the Middle East. Its practice is based on Jewish history and beliefs. It is one of the most popular religions in the world and has been for more than two thousand years.
Jewish people believe that God created everything and that all humans are created in the image of God. Judaism believes that God will judge each of us at the end. It is different than other religions, as it has many traditions, holidays and rules. There are 5 million Jews in the United States today. There are thousands upon thousands of synagogues across the country. The Jewish people believe in helping other people and making the world a better place.
The Torah portrays polytheism as a wicked and false religion. Deuteronomy32.16-17 reveals that God accuses the Israelites from worshipping false gods. Modern scholarship indicates that polytheism is rooted in monotheistic movements and is a more complex question than most people believe.

Zoroastrianism
Zoroastrianism, despite being one of the most small religions on the planet, still has an impact on the worldviews of its followers. The teachings of Zoroastrianism include the doctrines of hell, heaven, the Judgment Year, and freewill. It also teaches demons and angels.
Zoroastrians believe that humans can attain perfection in their current lives and then continue to meditate on the deeds they did in the next. A good balance of actions and deeds will lead to heaven, while an unhealthy balance will bring you to your death. Zoroastrianism encourages individuals to be good and moral beings.
Zoroastrianism is considered the oldest living religion in the world. Its followers were a well-off minority who believed strongly in education, honesty, respect, as well as respect. They eventually fled to India, where today they are called the Parsis.
