Foundations of Islam

Islam is a complete way of life that unites belief and practice. Faith in the heart and actions in daily life are not separate but connected. What Muslims believe shapes how they live, and how they live reflects what they believe. This guide introduces the essential beliefs and practices of Islam in a simple and accessible way.

Beliefs

Muslims hold six fundamental beliefs (the Six Pillars of Faith). These are summarized briefly below, each illustrated with a Qur’an verse.

  • Belief in Allah (One God): Islam teaches that there is one God, called Allah. He alone is worthy of worship. The Qur’an affirms the absolute uniqueness of God: “Allah ˹Himself˺ is a Witness that there is no god ˹worthy of worship˺ except Him” (Qur’an 3:18). This means no one and nothing else has divine status. Muslims believe Allah is eternal, without partners or equals.
  • Belief in Angels: Muslims believe in angels – invisible beings created by Allah to carry out His commands. For example, Angel Gabriel (Jibril) delivered Allah’s revelation to the prophets. The Qur’an says “All praise is for Allah, the Originator of the heavens and the earth, Who made angels ˹as His˺ messengers with wings…” (Qur’an 35:1). Angels always obey Allah and never disobey Him. Belief in angels reminds Muslims that Allah’s plan is carried out perfectly, even if we cannot see it.
  • Belief in Divine Books: Muslims believe Allah revealed holy books as guidance for people. The Qur’an itself is the final revealed book. Earlier scriptures (like the Torah given to Moses, the Gospel given to Jesus, and others) are also part of Islamic belief. The Qur’an notes that believers “They ˹all˺ believe in Allah, His angels, His Books, and His messengers.” (Qur’an 2:285). In other words, Muslims accept the original revelations from Allah. The Quran is believed to be preserved, while earlier scriptures are respected in their true forms. All of these books teach similar essence from Allah.
  • Belief in Messengers (Prophets): Muslims believe Allah sent prophets (messengers) to every nation throughout history. Prophets include figures like Adam, Noah, Abraham, Moses, Jesus, and Muhammad (peace be on them all). The Qur’an says Muslims “make no distinction between any of His messengers” (Qur’an 2:285). This means all prophets are respected. Muhammad is regarded as the final prophet, but believers honor the message of every prophet. These messengers taught how to worship Allah and live good lives, guiding people to the same faith in one God.
  • Belief in the Last Day (Day of Judgment): Muslims believe in life after death and a final Day of Judgment. The Qur’an says, “Every soul will taste death. And you will only receive your full reward on the Day of Judgment.” (Qur’an 3:185). This means everyone will rise again and be judged by Allah for their deeds. Belief in the Last Day inspires Muslims to live ethically and prepare for the hereafter, knowing they will be rewarded or held accountable.
  • Belief in Divine Decree (Qadar): Muslims believe that everything that happens is by Allah’s will and knowledge. This includes both good and bad events. The Qur’an explains, “No calamity ˹or blessing˺ occurs on earth or in yourselves without being ˹written˺ in a Record before We bring it into being” (Qur’an 57:22). In other words, nothing happens by chance outside of Allah’s plan. Believing in divine decree means trusting that Allah knows what is best, even if people do not immediately understand why something happens. For example, talents or opportunities and even natural events are seen as part of Allah’s wisdom and plan.

Practices

The Five Pillars of Islam are the basic acts of worship that shape a Muslim’s daily life. They are practiced by all Muslims and support the core beliefs.

  • Shahadah (Declaration of Faith): This is the Muslim profession of faith: “There is no god but Allah; Muhammad is the Messenger of Allah.”. Saying the shahadah sincerely makes one a Muslim. It affirms belief in the oneness of God and in Muhammad’s prophethood. The Qur’an itself confirms Muhammad’s role: “Muhammad is the Messenger of Allah” (Qur’an 48:29). The shahadah is repeated often in prayer and daily life, reminding Muslims of these central truths.
  • Salah (Prayer): Muslims pray five times each day as a direct link to Allah. These prayers are performed at dawn, midday, afternoon, sunset, and evening. Prayer helps Muslims stay mindful of Allah throughout the day. The Qur’an commands believers to “establish prayer and give zakah” (Qur’an 2:110), showing its importance. Prayer involves standing, bowing, and prostrating while reciting verses from the Qur’an. It is a moment of humility and remembrance. For example, when Muslims pray, they often face the Kaaba in Mecca and recite words of praise and supplication, seeking Allah’s guidance and mercy.
  • Zakah (Charity): This is the giving of a fixed portion (usually 2.5%) of one’s wealth each year to help the poor and needy. Zakah purifies one’s wealth and helps reduce economic inequality. It is required for those who can afford it. The importance of charity is linked with prayer in the Qur’an: “establish prayer and give zakah” (Qur’an 2:110). In practice, Muslims calculate their savings and give zakah to approved causes or through mosques during the year. For example, paying zakah may involve donating to help fund food, education, or medical aid for the less fortunate. It is seen as an act of worship that benefits the entire community.
  • Sawm (Fasting during Ramadan): Each year in the month of Ramadan (the ninth lunar month), adult Muslims fast from dawn until sunset. This means they do not eat or drink during daylight hours. Fasting is intended to foster self-discipline and empathy for the hungry. The Qur’an states, “O believers! Fasting is prescribed for you—as it was for those before you—so perhaps you will become mindful ˹of Allah˺” (Qur’an 2:183). In other words, fasting is not just abstaining from food, but also from sinful behavior. By experiencing hunger and thirst, Muslims gain compassion and spiritual insight. They break the fast at sunset with dates and water (as the Prophet Muhammad did) and pray together as a community.
  • Hajj (Pilgrimage to Mecca): Hajj is the pilgrimage to the holy city of Mecca in Saudi Arabia, required once in a lifetime for those who are physically and financially able. It occurs in the twelfth month of the Islamic calendar. Hajj includes specific rites such as circling the Kaaba and standing on Mount Arafat. The Qur’an explains this duty: “In it are clear signs and the standing-place of Abraham. Whoever enters it should be safe. Pilgrimage to this House is an obligation by Allah upon whoever is able among the people. And whoever disbelieves, then surely Allah is not in need of ˹any of His˺ creation.” (Qur’an 3:97). The pilgrimage commemorates the faith of Prophet Abraham and his family. During Hajj, Muslims from around the world come together in unity, wearing simple garments that erase social distinctions, all focused on worshipping Allah. Completing the Hajj is a powerful spiritual experience, signifying equality and submission to Allah.

These six beliefs and five practices work together to guide a Muslim’s life. They build a framework for understanding God’s purpose and living ethically. The Qur’an and the example of the Prophet Muhammad (peace be on him) provide further details for each point, which can be studied in more depth over time.
