Understanding Islam: Origins, Beliefs, and Core Practices

Islam is one of the world’s major religions, with over 1.8 billion followers across the globe. More than a belief system, Islam offers a complete worldview that shapes the moral, social, legal, and spiritual dimensions of life. To truly understand Islam, one must explore its historical roots, central doctrines, sacred texts, and core practices that guide its adherents from birth to death.

The Origins of Islam

Historical Context: Arabia in the 7th Century

Islam emerged in the early 7th century CE in the Arabian Peninsula, a region characterized by tribal loyalties, oral traditions, and widespread polytheism. The city of Mecca was a prominent religious and commercial hub, home to the Kaʿbah—a cube-shaped sanctuary believed by Muslims to have been originally built by Prophet Abraham (Ibrāhīm) and his son Ishmael (Ismāʿīl) as a house of monotheistic worship.

However, by Muhammad’s time, the Kaʿbah had become filled with idols representing various deities worshipped by the pagan Arab tribes.

The Life of Prophet Muhammad ﷺ

Muhammad ibn ʿAbdullāh was born around 570 CE into the noble Quraysh tribe of Mecca. Orphaned early in life, he was raised by his grandfather and then his uncle. Known for his honesty and integrity, he earned the nickname Al-Amīn (The Trustworthy).

At the age of 25, he married Khadījah bint Khuwaylid, a respected businesswoman, who became his first follower and strongest supporter.

The First Revelation and Early Mission

At the age of 40, while meditating in the Cave of Ḥirāʾ, Muhammad received the first revelation through the angel Jibrīl (Gabriel). The command was:

"Recite in the name of your Lord who created..." (Qur’an 96:1)

This event marked the beginning of 23 years of revelation, eventually compiled into the Qur’an, considered by Muslims to be the literal and final word of God (Allah). His message of Tawḥīd (pure monotheism), social justice, and moral rectitude challenged the dominant beliefs and power structures of Meccan society.

The Hijrah and the Rise of the Islamic Community

Due to escalating persecution, Muhammad and his followers migrated to the city of Yathrib (later called Madīnah) in 622 CE, an event known as the Hijrah. This migration marks year one of the Islamic calendar.

In Madīnah, Muhammad became both a spiritual and political leader. The city became the first Islamic state, governed by principles of justice, mutual cooperation, and divine law. By the time of his death in 632 CE, most of the Arabian Peninsula had embraced Islam.

Core Beliefs in Islam (ʿAqīdah)

Islam is based on six fundamental beliefs, known as the Articles of Faith (ʿAqāʾid), and expressed through five essential acts of devotion, called the Five Pillars (Arkān al-Islām).

1. Belief in One God (Tawḥīd)

Islam teaches absolute monotheism. Allah is the one and only deity—without partners, offspring, or likeness. He is described as All-Knowing, All-Powerful, Merciful, and Just.

The Islamic creed (shahādah) affirms this:

“Lā ilāha illa Allāh, Muḥammadun Rasūl Allāh”
“There is no god but Allah, and Muhammad is the Messenger of Allah.”

2. Belief in Angels (Malāʾikah)

Angels are created from light and serve as agents of God’s will. They do not possess free will.

Key angels include:

  • Jibrīl (Gabriel): The angel of revelation.

  • Mīkāʾīl (Michael): Oversees provision and rain.

  • ʿIzrāʾīl: Angel of death.

  • Kirāman Kātibīn: Record a person’s good and bad deeds.

3. Belief in Divine Scriptures (Kutub)

Muslims affirm that God revealed scriptures to specific prophets:

  • Tawrāh (Torah) to Mūsā (Moses)

  • Zabūr (Psalms) to Dāwūd (David)

  • Injīl (Gospel) to ʿĪsā (Jesus)

  • Ṣuḥuf (Scrolls) to Ibrāhīm (Abraham)

However, only the Qur’an is believed to remain unaltered and preserved in its original form.

4. Belief in the Prophets (Nubuwwah)

Prophets (nabī, plural: anbiyāʾ) are chosen humans sent to guide humanity. Islam teaches that every nation received a prophet (Qur’an 16:36), but Muhammad ﷺ is the final prophet, referred to as:

“Khatam an-Nabiyyīn” (Seal of the Prophets) – Qur’an 33:40

From Adam to Noah, Abraham, Moses, Jesus, and Muhammad, all called to the worship of the one true God.

5. Belief in the Day of Judgment (Yawm al-Qiyāmah)

Muslims believe in a final day when all individuals will be resurrected and judged based on their deeds. Paradise (Jannah) is the reward for the righteous; Hellfire (Jahannam) awaits those who reject God or do evil.

6. Belief in Divine Decree (Qadar)

Muslims believe that God’s knowledge encompasses everything. While humans have free will, all outcomes ultimately unfold according to God’s eternal wisdom and decree.

The Five Pillars of Islam (Arkān al-Islām)

These are the foundational acts of worship every Muslim must uphold:

1. Shahādah (Declaration of Faith)

“There is no god but Allah, and Muhammad is the Messenger of Allah.”

This testimony affirms belief in Tawḥīd and Muhammad’s final prophethood.

2. Ṣalāh (Ritual Prayer)

Muslims pray five times daily: at dawn (Fajr), noon (Ẓuhr), afternoon (ʿAsr), sunset (Maghrib), and night (ʿIshāʾ). Prayer involves reciting Qur’anic verses while facing the Kaʿbah in Mecca.

3. Zakāh (Obligatory Charity)

A fixed portion (usually 2.5%) of one’s wealth is given annually to the poor. Zakāh purifies wealth and reduces economic disparity.

4. Ṣawm (Fasting in Ramadan)

Muslims fast from dawn to sunset during the month of Ramadan, refraining from food, drink, and other physical needs. It fosters self-discipline and spiritual consciousness.

5. Ḥajj (Pilgrimage to Mecca)

Every able Muslim must perform Ḥajj at least once in their lifetime. The pilgrimage includes rituals that trace the legacy of Abraham, Hagar, and Ishmael, emphasizing submission to God.

The Qur’an and Hadith: Foundations of Islamic Teaching

The Qur’an

The Qur’an is the literal speech of God revealed in Arabic over 23 years. It covers theology, morality, law, history, and guidance for personal and communal life.

“This is the Book about which there is no doubt, a guidance for the righteous.” (Qur’an 2:2)

Hadith Literature

The Hadith are recorded sayings, actions, and approvals of Muhammad ﷺ. Authenticated collections such as Ṣaḥīḥ al-Bukhārī and Ṣaḥīḥ Muslim serve to interpret and implement the Qur’an.

Sharīʿah: Islamic Law

Sharīʿah is the comprehensive legal and ethical system derived from the Qur’an and Hadith. It governs areas including:

  • Personal conduct

  • Family and marriage law

  • Criminal and civil justice

  • Business and financial transactions

Schools of jurisprudence (madhāhib) in Sunni Islam include:

  • Ḥanafī

  • Mālikī

  • Shāfiʿī

  • Ḥanbalī

Shia Islam follows its own school of law, known as Jaʿfarī fiqh.

Sunni and Shia: The Two Major Branches

Sunni Islam

Comprises approximately 85–90% of Muslims. Emphasizes the consensus of the community (ijmāʿ) and accepts the first four caliphs as rightly guided successors of the Prophet.

Shia Islam

Holds that leadership (imāmah) should have remained within the Prophet’s family, beginning with his cousin and son-in-law ʿAlī ibn Abī Ṭālib. Shia Islam emphasizes the role of the Imams as spiritual and political leaders.

Despite theological and legal differences, both groups share the core tenets of Islam.

Islam in the Contemporary World

Muslims live in every part of the globe and contribute to diverse fields including science, art, politics, and ethics. While some uphold classical interpretations, others seek to engage Islamic teachings with modern challenges such as:

  • Gender roles

  • Freedom and governance

  • Human rights

  • Interfaith dialogue

Debates within the Muslim world continue over how to balance tradition with change.

Conclusion

Islam is a global faith rooted in the belief in one God, moral accountability, and guidance through divine revelation. Its history, beliefs, and practices form a comprehensive way of life for nearly a quarter of the world’s population. Whether studied through its theology, legal system, or cultural contributions, Islam calls for reflection on humanity’s relationship with the Creator and with one another.

The Problematic Elevation of Hadith Over the Qur’an: A Critical Polemic Response to “Why Do Islamic Scholars Sometimes Prioritize Hadith Over Qur’anic Verses?” Introduction: The Qur’an or the Hadith — Which Truly Commands Authority? Islamic scholarship claims the Qur’an is the ultimate, unaltered word of God. Yet, the very same scholars often insist that hadith—the human-recorded sayings and actions of Muhammad—sometimes override or clarify the Qur’an itself. This contradictory stance raises serious questions about textual integrity, theological consistency, and the real source of Islamic law and morality. If the Qur’an is “the Book about which there is no doubt” (Qur’an 2:2), why do we find thousands of rulings and laws being sourced primarily from hadith, often at the expense of clear Qur’anic principles? This post critically examines the logic, consequences, and hidden assumptions behind this practice. 1. The Qur’an’s Primacy Is Undermined by Overreliance on Hadith While t...

The Line of Prophets – A Continuation of the Message Isa (Jesus) – The Honored Messiah and Servant of Allah In the Islamic tradition, few prophets occupy as revered and central a place as ʿĪsā ibn Maryam (Jesus, son of Mary) . He is one of the five Ulū al-ʿAzm — the elite messengers distinguished for their endurance and unwavering resolve — along with Nūḥ, Ibrāhīm, Mūsā, and Muḥammad (peace be upon them all). His life, miracles, and eschatological role are discussed across over ninety verses in fifteen different surahs of the Qur’an, and he is referred to by name twenty-five times. Islam presents ʿĪsā not as divine, nor as the Son of God, but as a messenger of Allah , a spirit from Him (rūḥ minhu) , and His word cast upon Mary (kalimatuhu alqāhā ilā Maryam) . He was sent specifically to Banī Isrāʾīl (the Children of Israel) to revive the message of pure tawḥīd (monotheism), to confirm the Torah, and to deliver the Injīl , a scripture filled with light and guidance. A Miraculo...

  Before Islam: Decoding the Earliest Sources on Muhammad’s Movement Islamic tradition paints a vivid picture: in 610 CE, Muhammad received divine revelations in a Meccan cave, birthing Islam—a fully formed monotheistic faith with scripture, rituals, and law. Yet, the earliest non-Muslim records—Syriac, Greek, and Armenian chronicles from the 7th century—tell a starkly different story. They mention no “Islam,” no “Qur’an,” and no prophet preaching a new creed. Instead, Muhammad’s followers appear as “Hagarenes,” “Ishmaelites,” or “Saracens”—vague monotheists or tribal raiders acting under divine sanction. This evidence challenges the claim of a coherent religion descending from heaven, suggesting a fluid insurgency later mythologized into divine revelation by Abbasid scholars. This post dives into these sources, their context, and their implications, testing Islam’s narrative against the Qur’an’s own standards—proof ( Surah 2:111 ) and consistency ( Surah 4:82 ). The Islamic Narrat...
