among Mahometans, a fabulous animal, supposed to be of the middle kind between an ass and a mule, whereon their prophet was carried in his nocturnal flight from Jerusalem into the heavens. This animal the Arabians call Al-Borak, q. d. shining. The night when the journey was performed is called Lailat al-Miraj, i.e. the night of ascension; and the flight itself Al-Mefra; concerning which there are a multitude of traditions.
