Night of Power in the context of "Angels in Islam"

The Quran (vocalized Arabic: الْقُرْآن‎, Quranic Arabic: الۡقُرۡءَان‎, al-Qurʾān [alqurˈʔaːn], lit. 'the recitation' or 'the lecture'), also romanized Qur'an or Koran, is the central religious text of Islam, believed by Muslims to be a revelation directly from God (Allāh). It is organized in 114 chapters (surah, pl. suwar) which consist of individual verses (āyah). Besides its religious significance, it is widely regarded as the finest work in Arabic literature, and has significantly influenced the Arabic language. It is the object of a modern field of academic research known as Quranic studies.

Muslims believe the Quran was orally revealed by God to the final Islamic prophet Muhammad through the angel Gabriel incrementally over a period of some 23 years, beginning on the Laylat al-Qadr, when Muhammad was 40, and concluding in 632, the year of his death. Muslims regard the Quran as Muhammad's most important miracle, a proof of his prophethood, and the culmination of a series of divine messages starting with those revealed to the first Islamic prophet Adam, including the holy books of the Torah, Psalms, and Gospel in 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.
