In one minute

Islam means 'submission' to the will of the One God, Allah, and a follower is called a Muslim. Muslims believe that God sent many prophets, among them Adam, Ibrahim (Abraham), Musa (Moses) and Isa (Jesus), and that the final prophet was the Prophet Muhammad (peace be upon him), to whom the Quran was revealed in 7th-century Arabia. Muslim life is built on faith in God's oneness (tawhid), the Five Pillars of worship, and the guidance of the Quran and the example of the Prophet. Islam is followed across the world, and India is home to one of the largest Muslim populations of any country.

In India (Census 2011): 17.22 crore (14.2%)

Origins

As the tradition tells it

Muslims believe that Islam is the original faith of humanity, taught by every prophet from Adam onward, and that the Kaaba in Mecca was raised for the worship of the One God by the prophet Ibrahim and his son Ismail. In about 610 CE, while the Prophet Muhammad (peace be upon him) was meditating in the Cave of Hira near Mecca, Muslims believe the angel Jibril (Gabriel) brought him the first revelation of the Quran. Revelations continued for about 23 years. In 622 CE the Prophet and his followers migrated to Medina (the Hijra), where the first Muslim community took shape.

As historians describe it

Historians place the life of the Prophet Muhammad (peace be upon him) at about 570 to 632 CE, in Mecca and Medina in western Arabia, a region of trading towns and tribal societies. Early sources include the Quran itself, later collections of hadith and the biographies (sira) written in the 8th and 9th centuries. Most historians date the standard written text of the Quran to the time of the third caliph, Uthman, around 650 CE, and early manuscripts support a fixed text from an early date. Within a century of the Prophet's death, Muslim rule and communities extended from Spain to Central Asia and Sindh.

Core teachings

Tawhid: the oneness of God

In Islam, the central belief is that God (Allah) is One, without partner or equal, the merciful Creator of all. The declaration of faith, the shahada, states: 'There is no god but God, and Muhammad (peace be upon him) is the Messenger of God.'

Prophets and revealed books

Muslims believe God sent prophets to every people, including Nuh, Ibrahim, Musa and Isa, and revealed scriptures such as the Tawrat, the Zabur and the Injil. They believe the Prophet Muhammad (peace be upon him) is the last of the prophets and the Quran is the final revelation.

The Five Pillars

Muslims practise five pillars of worship: the shahada (declaration of faith), salah (prayer five times a day facing the Kaaba), zakat (giving a share of wealth to those in need), sawm (fasting in the month of Ramadan) and Hajj (pilgrimage to Mecca once in a lifetime for those able).

Angels, the Last Day and divine decree

Along with belief in God, the prophets and the revealed books, Muslims believe in angels, in a Day of Judgement when all will answer for their deeds, and in God's decree. Together these are often called the articles of faith (iman).

Mercy, justice and good character

Muslims are taught that God is Ar-Rahman and Ar-Rahim, the Most Gracious and Most Merciful, and every chapter of the Quran but one opens with these names. Islam stresses honesty, care for parents, neighbours, orphans and the poor, and justice in dealings as part of worship.

Sharia and the Sunnah

Muslims seek to live by the Sharia, the path of guidance drawn from the Quran and the Sunnah, the example of the Prophet Muhammad (peace be upon him) recorded in hadith. Scholars interpret it through schools of law, covering worship, family life and ethics.

Sacred books

📖 The Quran ›

Muslims believe the Quran is the word of God revealed to the Prophet Muhammad (peace be upon him) through the angel Jibril over about 23 years. It has 114 chapters (surahs) in Arabic; Muslims regard the Arabic text as the Quran itself and translations as renderings of its meanings.

Schools and communities

Where traditions within this faith differ. Described side by side, with no verdict.

Sunni Islam

The larger branch worldwide and in India. Sunnis hold that leadership after the Prophet Muhammad (peace be upon him) passed rightly to the elected caliphs, beginning with Hazrat Abu Bakr. They follow four schools of law (Hanafi, Maliki, Shafii and Hanbali); most Indian Sunnis are Hanafi, while many in Kerala and the Konkan are Shafii.

Shia Islam

Shia Muslims believe the Prophet Muhammad (peace be upon him) appointed Hazrat Ali as his successor and that leadership continued through the Imams of his family. Most Indian Shias are Twelvers (Ithna Ashari), with centres such as Lucknow and Hyderabad; Ismaili communities include the Dawoodi Bohras and the Khojas who follow the Aga Khan.

Sufi traditions

Sufism is the inner, mystical path of Islam, found among both Sunni and Shia Muslims, seeking closeness to God through remembrance (dhikr), love and discipline under a spiritual guide. In India the Chishti, Qadiri, Suhrawardi and Naqshbandi orders have been influential, and their dargahs and qawwali music are part of shared culture.

Sunni movements in South Asia

Among Indian Sunnis, several scholarly movements arose in the 19th century, such as the Deobandi, Barelvi and Ahl-e-Hadith. They differ mainly on matters such as devotion at Sufi shrines, celebrations of the birthday of the Prophet Muhammad (peace be upon him) and how closely to follow a school of law.

Festivals

  • Ramadan: The ninth month of the Islamic calendar, when Muslims fast from dawn to sunset, pray more and give in charity; the fast is opened at iftar. Because the Hijri calendar is lunar, Ramadan moves about 11 days earlier each year.
  • Eid al-Fitr: The festival that ends Ramadan, marked by special prayers, zakat al-fitr for the poor, new clothes, family visits and sweets such as sheer khurma.
  • Eid al-Adha (Bakrid): Held during the Hajj season, it recalls the devotion of the prophet Ibrahim; families offer a sacrifice (qurbani) and share the meat with relatives, neighbours and the poor.
  • Muharram and Ashura: Muharram begins the Islamic year. On its tenth day, Ashura, Shia Muslims mourn Imam Husayn with majlis gatherings and processions, while many Sunni Muslims observe a voluntary fast.
  • Milad un-Nabi: Many Muslims mark the birth of the Prophet Muhammad (peace be upon him) in the month of Rabi al-Awwal with recitations of poetry in his praise and gatherings; some Muslim groups do not hold special celebrations for it.
  • Shab-e-Barat: The night of the 15th of Shaban, observed by many South Asian Muslims with prayer, seeking forgiveness and visiting the graves of loved ones.

In India today

Islam reached India early through Arab traders on the Malabar coast, where the Mappila Muslims of Kerala trace their community to the first centuries of Islam. Over the following centuries Sufi saints of the Chishti and other orders settled across the subcontinent, and their dargahs became places visited by people of many faiths. Indian Muslims are very diverse: they include Urdu-speaking communities of north India and the Deccan, Bengali, Gujarati, Tamil and Konkani Muslims, the Dawoodi Bohras and Khojas, and the people of Lakshadweep, where most residents are Muslim. Indo-Islamic architecture, the Urdu language, qawwali and many shared traditions of food and craft are part of India's common heritage.

Visiting and learning with respect

  • Remove your shoes before entering the prayer area of a mosque or dargah, and dress modestly with arms and legs covered; women are usually asked to cover their hair, and many dargahs ask men to cover their heads too.
  • Visit outside the five daily prayer times if you can, and never walk directly in front of someone who is praying.
  • Handle a copy of the Quran with clean hands and respect, and do not place it on the floor.
  • During Ramadan, it is courteous not to eat or drink in front of people who are fasting where you can avoid it; a common greeting is 'Assalamu alaikum' (peace be upon you), answered with 'Wa alaikum assalam'.
