The framework of Muslim worship
The practice of Islam rests on five duties known as the Five Pillars. They are the acts of worship every Muslim is expected to uphold, and together they shape daily life, the yearly calendar, and a lifetime of faith.789 The Prophet Muhammad ﷺ named them directly:
"Islam is built upon five [pillars]: the testimony that there is no god but Allah and that Muhammad is the Messenger of Allah, the establishment of prayer, the giving of zakat, the pilgrimage (Hajj), and fasting in Ramadan."
— Sahih al-Bukhari 81
1. Shahada — the declaration of faith
The first pillar is to bear witness that there is no god but Allah, and Muhammad ﷺ is His Messenger. It is the gateway to Islam and the belief underlying the other four pillars.
"So know that there is no deity except Allah."
— Quran 47:19 (Saheeh International)2
2. Salah — the five daily prayers
Muslims pray five times a day at appointed times, facing the Kaaba in Mecca. Prayer is the most frequent act of worship and is repeatedly paired with charity in the Quran:
"And establish prayer and give zakat, and bow with those who bow [in worship]."
— Quran 2:43 (Saheeh International)3
3. Zakat — obligatory almsgiving
Zakat is a fixed annual share of one's accumulated wealth, given to those in need. It is an act of worship and of social justice — a right the poor hold over the wealthy. The Quran specifies who may receive it:
"Zakat expenditures are only for the poor and for the needy and for those employed to collect it … and for those in debt and for the cause of Allah and for the [stranded] traveler."
— Quran 9:60 (Saheeh International)4
4. Sawm — fasting in Ramadan
During the month of Ramadan, Muslims fast from dawn until sunset, abstaining from food, drink, and other needs, devoting themselves to worship and self-restraint:
"O you who have believed, decreed upon you is fasting as it was decreed upon those before you, that you may become righteous."
— Quran 2:183 (Saheeh International)5
5. Hajj — the pilgrimage to Mecca
Once in a lifetime, every Muslim who is physically and financially able must perform the Hajj, the pilgrimage to the Kaaba in Mecca:
"And [due] to Allah from the people is a pilgrimage to the House — for whoever is able to find thereto a way."
— Quran 3:97 (Saheeh International)6
In short
The Five Pillars — Shahada, Salah, Zakat, Sawm, and Hajj — are the core acts of worship in Islam. The declaration of faith establishes belief; prayer and fasting nurture it daily and yearly; zakat turns it toward others; and the pilgrimage gathers Muslims from across the world in a single act of devotion.
