Laylat al-Qadr, or the night of power, is considered by Muslims to be the holiest night of Ramadan, the Islamic holy month of fasting.
The exact date of Laylat al-Qadr is disputed, but it is believed to have occurred on one of the last 10 days of the month.
Many Muslims believe it is either the night of the 27th day of Ramadan, or one of the odd-numbered nights during the final 10 days of the month.
