Laylat Al-Qadr

Laylat al-Qadr (Arabic: لیلة القدر‎) (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.
