Islam is the religion of roughly a quarter of the world’s population. Its central claim is short enough to state in a sentence: there is one God, He has spoken to humanity through prophets, and the last of those prophets was Muhammad (peace be upon him).
Everything else, the prayers and the fasting and the law and the fourteen centuries of scholarship, is an attempt to live consistently with that sentence.
The word itself
The Arabic root s-l-m carries two meanings at once: peace and submission. Islām is the act of handing something over, of placing yourself willingly in the care of God. A muslim is simply the one who does that.
The two meanings are not in tension. The claim being made is that peace is what follows from stopping the argument with reality and accepting the One who made it.
By this definition, Islam does not present itself as a new religion that began in the seventh century. It presents itself as the original one, taught by every prophet from Adam onward, and restored each time it was lost.
One God, and nothing beside Him
The heart of Islam is tawḥīd, the oneness of God. Not one god among several. Not one god who is three. One, without partner, without offspring, without division, and without any likeness among the things He made.
قُلْ هُوَ اللَّهُ أَحَدٌ اللَّهُ الصَّمَدُ لَمْ يَلِدْ وَلَمْ يُولَدْ وَلَمْ يَكُنْ لَهُ كُفُوًا أَحَدٌ
Allah is not the name of a particular tribal deity. It is the Arabic word for God, and it is the word Arabic-speaking Christians and Jews use for God in their own scriptures and liturgy. Its grammar is worth noticing: it takes no plural and no gender.
The practical consequence of tawḥīd is directness. There is no priesthood in Islam and no intercessor between a person and God. Anyone, anywhere, in any language, can address Him without permission and without appointment.
Where the Qur’an came from
Muslims believe that in the year 610, in a cave outside Mecca, a man of forty who could not read was told to read. The revelation continued in pieces for twenty-three years, and what accumulated is the Qur’an: 114 chapters, roughly the length of the New Testament.
Two things about it are worth knowing even if you never open it.
The first is that it was preserved as sound before it was preserved as text. It was memorised as it came, recited back, and cross-checked against other memorisers. That practice never stopped. In every generation since, including this one, there have been people who hold the entire book in memory. The Arabic text a reader picks up in Jakarta and the one picked up in Casablanca are the same text.
The second is that Muslims do not regard translations as the Qur’an. A translation is a translation: useful, necessary, and not the thing itself. This is why Arabic occupies the place in Islam that it does, and also why not knowing Arabic has never been a barrier to being Muslim.
The Prophet
Muhammad (peace be upon him) is not worshipped, and Muslims are not “Muhammadans.” He is understood as a man, one who ate and slept and grieved and made mistakes in worldly matters and was corrected, and through whom the final revelation came.
What Muslims take from him is not only the message but the manner: how he treated servants, opponents, animals, children, and the people who had tried to kill him. The Qur’an calls him a beautiful example, and the word it uses for example is uswah.
لَقَدْ كَانَ لَكُمْ فِي رَسُولِ اللَّهِ أُسْوَةٌ حَسَنَةٌ
That verse is where this site takes its name.
What Islam asks of a person
Less than people often assume, and more consistently.
There are five obligations that structure a Muslim’s life: the testimony of faith, five daily prayers, an annual portion of surplus wealth given to the poor, fasting through the month of Ramadan, and one pilgrimage to Mecca for those who can manage it. These are the pillars, and none of them takes very long. The prayer is a few minutes; what makes it demanding is that it comes back five times a day, every day, whatever else is happening.
Alongside them is a body of ethics that occupies far more of the Qur’an than ritual does: honesty in trade, restraint in speech, care for parents in their old age, keeping your word, feeding people, and not humiliating anyone. Islam is unusually specific about small obligations. Removing something harmful from a public road is described as an act of faith.
Islam and the faiths before it
Islam does not regard Judaism and Christianity as foreign religions. Their prophets are its prophets. Moses is named in the Qur’an more often than Muhammad. Jesus (peace be upon him) is held to be a prophet born of a virgin, who healed the sick and raised the dead by God’s permission. Mary is the only woman the Qur’an names, and an entire chapter bears her name.
The disagreement is real and it is specific: Islam does not accept that God has a son, or that any human being is divine. On that point it does not compromise. On the question of coercion, it also does not:
لَا إِكْرَاهَ فِي الدِّينِ
Where to go next
If you want the life behind the message, read about the Prophet. If you want the practices, read the pillars. If you want to know what God is called and what those names mean, see the ninety-nine names. And if you have the ordinary blunt questions about violence, about women, about how a person actually converts, those are answered here.
