Firdous e Bareen (Persian: فردوس برین‎) was the name of the ancient Persian garden, supposedly located in the fortress of Alamut, in the Elburz mountains of Northern Iran, in which Hassan-i-Sabah and his band of Nizari Ismaili Shiite Hashshashin took refuge. The novel , written by Indian Muslim novelist Abdul Halim Sharar, gives a biographical account of Hussain, a youth lured and captured by Sabah's men and then forced into his assassination machinery. Firdous e Bareen is also a song on the album In the Absence of Truth by the American post-metal band Isis. * v * t * e * v * t * e
