Laylat al-Qadr (also known as Shab-e-Qadr), variously rendered in English as the Night of Destiny, Night of Power, Night of Value, the Night of Decree or Night of Measures, is the anniversary of two very important dates in Islam that occurred in the month of Ramadan. It is the anniversary of the night Muslims believe the first verses of the Quran were revealed to the Islamic prophet Muhammad.
This “Night of Power” is considered the most appropriate time of the entire year to pray for salvation and blessings. It is believed that a Muslim’s past sins are forgiven if the person prays throughout this night. Many people assemble at mosques during the Isha’ prayer, with many prayers being made until midnight.
Regional customs or moon sightings may cause a variation of the date for Islamic holidays, which begin at sundown the day before the date specified for the holiday. The Islamic calendar is lunar and the days begin at sunset, so there may be one-day error depending on when the New Moon is first seen.
