Qadr Night

Laylat al-Qadr () (also known as Shab-e-Qadr), basically  the Night of Decree or Night of Measures, is the anniversary of two very important dates in Islam. They occurred in the month of Ramadan. It is the anniversary of the night Muslims believe the first verses of the Qur'an were revealed to the Islamic prophet Muhammad.
