Dr Musharraf Hussain, the Chief Imam in the Karimia Institute in Nottingham, describes what is celebrated each year on the anniversary of the Ascension of the Prophet (the Mí'raj). This recalls a miraculous trip one night when the Prophet was taken from Mecca to Jerusalem, and then was taken on a tour of heaven and hell. This festival is kept with a vigil of prayer and a recollection of the miraculous ascension.
