Five Pillars of Islam in the context of "Twelver"

Islam is an Abrahamic monotheistic religion based on the Quran and the teachings of Muhammad. Adherents of Islam are called Muslims, who are estimated to number 2 billion worldwide and are the world's second-largest religious population, after Christianity.

Muslims believe that there is a primordial faith that was revealed many times through earlier prophets and messengers, including Adam, Noah, Abraham, Moses, and Jesus, and they believe that Islam is the universal and complete version of this faith. Muslims consider the Quran to be the verbatim word of God and the unaltered, final revelation. Alongside the Quran, Muslims also believe in previous revelations, such as the Tawrat (the Torah), the Zabur (Psalms), and the Injil (Gospel). They believe that Muhammad is the main and final of God's prophets, through whom the religion was completed. The teachings and normative examples of Muhammad, called the Sunnah, documented in accounts called the hadith, provide a constitutional model for Muslims. Islam is based on the belief in the oneness and uniqueness of God (tawhid), and belief in an afterlife (akhirah) with the Last Judgment—wherein the righteous will be rewarded in paradise (jannah) and the unrighteous will be punished in hell (jahannam). The Five Pillars, considered obligatory acts of worship, are the Islamic oath and creed (shahada), daily prayers (salah), almsgiving (zakat), fasting (sawm) in the month of Ramadan, and a pilgrimage (hajj) to Mecca. Islamic law, sharia, touches on virtually every aspect of life, from banking and finance and welfare to men's and women's roles and the environment. The two main religious festivals are Eid al-Fitr and Eid al-Adha. The three holiest sites in Islam are Masjid al-Haram in Mecca, Prophet's Mosque in Medina, and al-Aqsa Mosque in Jerusalem.

Hajj (/hɑːdʒ/; Arabic: حَجّ, romanized: Ḥajj; also spelled Hadj or Haj) is an annual Islamic pilgrimage to Mecca, Saudi Arabia, the holiest city for Muslims. Hajj is a mandatory religious duty for capable Muslims that must be carried out at least once in their lifetime by all adult Muslims who are physically and financially capable of undertaking the journey, and of supporting their family during their absence from home.

In Islamic terminology, Hajj is a pilgrimage made to the Kaaba, the "House of Allah", in the sacred city of Mecca in Saudi Arabia. It is one of the Five Pillars of Islam, alongside Shahadah (oath that one believes there is no god but Allah), salat (prayer), zakat (almsgiving), and sawm (fasting during Ramadan). The Hajj is an annual practice when Muslim brotherhood is on display and their solidarity with fellow Muslim people and submission to God (Allah) is fulfilled. The Hajj is taken by Muslims to cleanse their souls of all worldly sins, which connotes both the outward act of a journey after death and the inward act of good intentions. The rites of pilgrimage are performed over five to six days, extending from the 8th to the 12th or 13th of Dhu al-Hijjah, the last month of the Islamic calendar. Because the Islamic calendar is lunar and the Islamic year is about eleven-twelve days shorter than the Gregorian year, the Gregorian date of Hajj changes from year to year. In 2024 AD (1445 AH), Dhu al-Hijjah extended from 7 June to 6 July and in 2025 AD (1446 AH), Dhu al-Hijjah was from 28 May to 25 June. In 2026 AD (1447 AH), Dhu al-Hijjah will extend from 18 May to 15 June; and in 2027 AD (1448 AH), Dhu al-Hijjah will extend from 24 May to 22 June.

The Shahada (Arabic: الشَّهَادَةُ aš-šahādatu; Arabic pronunciation: [aʃʃahaːdatʊ], 'the testimony'), also transliterated as Shahadah, is an Islamic oath and creed, and one of the Five Pillars of Islam and part of the Adhan. It reads: "I bear witness that there is no god but God, and I bear witness that Muhammad is the Messenger of God."The Shahada declares belief in the oneness (tawhid) of God and the acceptance of Muhammad as God's messenger. Some Shia Muslims also include a statement of belief in the wilayat of Ali, but they do not consider it as an obligatory part for converting to Islam. A single honest recitation of the Shahada is all that is required for a person to become a Muslim according to most traditional schools.

Salah (Arabic: ٱلصَّلَاةُ, romanized: aṣ-Ṣalāh, also spelled Salat), also known as Namaz (Persian: نماز, romanized: namāz), is the practice of formal worship in Islam, consisting of a series of ritual prayers performed at prescribed times daily. These prayers, which consist of units known as rak'ah, include a specific set of physical postures, recitation from the Quran, and prayers from the Sunnah, and are performed while facing the direction towards the Kaaba in Mecca (qibla). The number of rak'ah varies depending on the specific prayer. Variations in practice are observed among adherents of different madhahib (schools of Islamic jurisprudence). The term salah may denote worship in general or specifically refer to the obligatory prayers performed by Muslims five times daily, or, in some traditions, three times daily.

The obligatory prayers play an integral role in the Islamic faith, and are regarded as the second and most important, after shahadah, of the Five Pillars of Islam for Sunnis, and one of the Ancillaries of the Faith for Shiites. In addition, supererogatory salah, such as Sunnah prayer and Nafl prayer, may be performed at any time, subject to certain restrictions. Wudu, an act of ritual purification, is required prior to performing salah. Prayers may be conducted individually or in congregation, with certain prayers, such as the Friday and Eid prayers, requiring a collective setting and a khutbah (sermon). Some concessions are made for Muslims who are physically unable to perform the salah in its original form, or are travelling.

Zakat (or Zakāh) is one of the Five Pillars of Islam. Zakat is the Arabic word for "giving to charity" or "giving to the needy". Zakat is a form of almsgiving, often collected by the Muslim Ummah. It is considered in Islam a religious obligation, and by Quranic ranking, is next after prayer (salat) in importance. Eight heads of zakat are mentioned in the Quran.

As one of the Five Pillars of Islam, zakat is a religious duty for all Muslims who meet the necessary criteria of wealth to help the needy. It is a mandatory charitable contribution, often considered to be a tax. The payment and disputes on zakat have played a major role in the history of Islam, notably during the Ridda wars.

In Islam, fasting (called ṣawm in Arabic: صَوم [sˤɑwm], or ṣiyām صيام [sˤɪˈjæːm]) is the practice of abstaining from food, drink, sexual activity, and anything that substitutes food and drink. During the holy month of Ramadan, fasting is observed between dawn and sunset when the prayer call of the dawn prayer and the sunset prayer is called. Ramadan is the ninth month of the Muslim lunar calendar and fasting is a requirement for able Muslims as it is the fourth of the five pillars of Islam.

Between the 9th and 14th centuries, the Muslim world developed many advanced economic concepts, techniques and usages. These ranged from areas of production, investment, finance, economic development, taxation, property use such as Hawala: an early informal value transfer system, Islamic trusts, known as waqf, systems of contract relied upon by merchants, a widely circulated common currency, cheques, promissory notes, early contracts, bills of exchange, and forms of commercial partnership such as mufawada.

Specific Islamic concepts involving money, property, taxation, charity and the Five Pillars include:
