Ramadan in the context of Gulf Standard Time

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.

The Hijri calendar (Arabic: ٱلتَّقْوِيم ٱلْهِجْرِيّ, romanized: al-taqwīm al-hijrī), also known in English as the Islamic calendar, is a lunar calendar consisting of 12 lunar months in a year of 354 or 355 days. It is used to determine the proper days of Islamic holidays and rituals, such as the annual fasting and the annual season for the great pilgrimage. In almost all countries where the predominant religion is Islam, the civil calendar is the Gregorian calendar, with Syriac month-names used in the Levant and Mesopotamia (Iraq, Syria, Jordan, Lebanon and Palestine), but the religious calendar is the Hijri one.

This calendar enumerates the Hijri era, whose epoch was established as the Islamic New Year in 622 CE. During that year, Muhammad and his followers migrated from Mecca to Medina and established the first Muslim community (ummah), an event commemorated as the Hijrah. In the West, dates in this era are usually denoted AH (Latin: Anno Hegirae, lit. 'In the year of the Hijrah'). In Muslim countries, it is also sometimes denoted as H from its Arabic form (سَنَة هِجْرِيَّة, abbreviated ھ). In English, years prior to the Hijra are denoted as BH ("Before the Hijra").

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 Five Pillars of Islam (arkān al-Islām أركان الإسلام; also arkān ad-dīn أركان الدين "pillars of the religion") are fundamental practices in Islam, particularly Sunni Islam, considered to be obligatory acts of worship for all Muslims. They are summarized in the hadith of Gabriel. The Sunni and Shia agree on the basic details of the performance and practice of these acts, but Shia denominations may have their own lists of pillars that differ from the Sunni five, such as the Twelver Ancillaries of the Faith (consisting of four pillars and six obligatory acts) and the Ismaili Seven Pillars. The five pillars are: profession of faith (Shahada), prayer (Salah), almsgiving (Zakat), fasting in the month of Ramadan (Sawm), and pilgrimage to Mecca (Hajj).

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.

There are two main holidays in Islam that are celebrated by Muslims worldwide: Eid al-Fitr and Eid al-Adha. The timing of both holidays are set by the lunar Islamic calendar, which is based upon the cycle of the moon, and so is different from the more common, European, solar-based Gregorian calendar. Every year, the Gregorian dates of the Islamic holidays change.

Both Eid al-Fitr and Eid al-Adha follow a period of 10 holy days or nights: the last 10 nights of Ramadan for Eid al-Fitr, and the first 10 days of Dhu al-Hijjah for Eid al-Adha. The Night of Power (Arabic: لیلة القدر, romanized: Laylat al-Qadr), one of the last 10 nights of Ramadan, is the holiest night of the year. Conversely, the Day of Arafah, the day before Eid al-Adha, is the holiest day of the Islamic year.

Eid al-Fitr (Arabic: عيد الفطر, romanized: ʿĪd al-Fiṭr, lit. 'Festival of Breaking the Fast') is the first of the two main festivals in Islam, the other being Eid al-Adha. It falls on the first day of Shawwal, the tenth month of the Islamic calendar. Eid al-Fitr is celebrated by Muslims worldwide as it marks the end of the month-long, dawn-to-dusk fasting (sawm) during Ramadan. The holiday is known under various other names in different languages and countries around the world.

Eid al-Fitr has a particular salah that consists of two rakats generally performed in an open field or large hall. It may only be performed in congregation (jamāʿat) and features six additional Takbirs (raising of the hands to the ears whilst reciting the Takbir, saying "Allāhu ʾAkbar", meaning "God is the greatest"). In the Hanafi school of Sunni Islam, there are three Takbirs at the start of the first rakat and three just before rukūʿ in the second rakat. Other Sunni schools usually have 12 Takbirs, similarly split in groups of seven and five. In Shia Islam, the salat has six Takbirs in the first rakat at the end of Tilawa, before rukūʿ, and five in the second. Depending on the juristic opinion of the locality, this salat is either farḍ (فرض, obligatory) or mustaḥabb (strongly recommended). After the salat, Muslims celebrate the Eid al-Fitr in various ways with food being a central theme, which also gives the holiday the nickname "Sweet Eid" or "Sugar Feast".

The Islamic New Year (Arabic: رأس السنة الهجرية, Raʿs as-Sanah al-Hijrīyah), also called the Hijri New Year, is the day that marks the beginning of a new lunar Hijri year, and is the day on which the year count is incremented. The first day of the Islamic year is observed by most Muslims on the first day of the month of Muharram. The epoch (reference date) of the Islamic era was set as the year of the emigration of Muhammad and his followers from Mecca to Medina, known as the Hijrah, which equates to 622 CE in the Gregorian calendar. All religious duties, such as prayer, fasting in the month of Ramadan, and pilgrimage, and the dates of significant events, such as celebration of holy nights and festivals, are calculated according to the Islamic calendar. Hijri New Year is observed by 24 countries as a public holiday.

While some Islamic organizations prefer determining the new month (and hence the new year) by local sightings of the moon, most Islamic institutions and countries, including Saudi Arabia, follow astronomical calculations to determine future dates of the Islamic calendar. There are various schemas for calculating the tabular Islamic calendar (i.e. not based on observation), which results in differences of typically one or even two days between countries using such schema and those that use actual lunar sightings. For example, the Umm al-Qura calendar used in Saudi Arabia was reformed several times in recent years. The current scheme was introduced in 1423 AH (15 March 2002).

In Islamic belief, Laylat al-Qadr (in Arabic: لیلة القدر) or Night of Power is an Islamic festival in memory of the night when Muslims believe the Quran was first sent down from heaven to the world, the first revelation the Islamic prophet Muhammad received from the angel Gabriel. The Night of Power belongs to one of the five Kandil Nights.

In the Quran, it is said this night is better than 1,000 months (approximately 83.3 years). According to various hadiths, the exact date of the night is uncertain, though it is believed to fall on one of the odd-numbered nights during the last ten days of Ramadan, the ninth month of the Islamic calendar. Since that time, Muslims have regarded the last ten nights of Ramadan as being especially blessed. Muslims believe the Night comes again every year, with blessings and mercy of God in abundance. The surah al-Qadr is named after this Night, and the chapter’s purpose is to describe the greatness of the occasion.

Greenwich Mean Time (GMT) is the local mean time at the Royal Observatory in Greenwich, London, counted from midnight. At different times in the past, it has been calculated in different ways, including being calculated from noon; as a consequence, it cannot be used to specify a particular time unless a context is given. The term "GMT" is also used as one of the names for the time zone UTC+00:00 and, in UK law, is the basis for civil time in the United Kingdom.

Because of Earth's uneven angular velocity in its elliptical orbit and its axial tilt, noon (12:00:00) GMT is rarely the exact moment the Sun crosses the Greenwich Meridian and reaches its highest point in the sky there. This event may occur up to 16 minutes before or after noon GMT, a discrepancy described by the equation of time. Noon GMT is the annual average (the arithmetic mean) moment of this event, which accounts for the word "mean" in "Greenwich Mean Time".

Khadija bint Khuwaylid (Arabic: خَدِيجَة بِنْت خُوَيْلِد) (c. 554 – November 619) was the first wife of Muhammad. Born into an aristocratic clan of the Quraysh, she was an affluent merchant in her own right and was known to have a noble personality within her tribe. She employed Muhammad to manage a trade caravan to Syria and, impressed by his skills, subsequently offered him marriage, which he accepted.

The couple had two sons, Qasim and Abd Allah, and four daughters, Zaynab, Ruqayya, Umm Kulthum and Fatima. In the aftermath of Muhammad's first revelation, Khadija is credited to have been the first convert to Islam. She continued to support her husband throughout her life and died in November 619 (Ramadan BH 3); the year was reportedly termed the "Year of Sorrow" by Muhammad. Her remains are located at the al-Mu'alla in Mecca and attract many Muslims for ziyarat.

Al-Baqarah (Arabic: الْبَقَرَة, ’al-baqarah; lit. "The Heifer" or "The Cow"), also spelled as Al-Baqara, is the second and longest chapter (surah) of the Quran. It consists of 286 verses (āyāt) which begin with the "muqatta'at" letters alif (ا), lām (ل), and mīm (م). The Verse of Loan (the longest single verse of the Quran), the Throne Verse (the greatest verse), and the last 2 verses, Treasures of the Throne are in this chapter.

The sūrah encompasses a variety of topics and contains several commands for Muslims such as enjoining fasting on the believer during the month of Ramadan; forbidding interest or usury (riba); and several other famous verses such as the last two verses, which came from the treasure under Allah's Throne, and the verse of no compulsion in religion.The sūrah addresses a wide variety of topics, including substantial amounts of law, and retells stories of Adam, Ibrahim (Abraham) and Mūsa (Moses). A major theme is guidance: urging the pagans (Al-Mushrikeen) and the Jews of Medina to embrace Islam, and warning them and the hypocrites (Munafiqun) of the fate God had visited in the past on those who failed to heed his call. The surah is also believed to be a means of protection from the jinn.

Iftar (Arabic: إفطار, romanized: ifṭār) is the fast-breaking evening meal of Muslims in Ramadan at the time of adhan (call to prayer) of the Maghrib prayer.

Iftar is the second meal of the day; during Ramadan, the daily fast begins immediately after the pre-dawn meal of suhur and continues during the daylight hours, ending at sunset with the evening meal of iftar.
