The nave contains a striking central row of columns adorned with every colour of prayer cloths. Before you tie a knot to make your wish, you must first untie a knot so that wish can be granted.
To the right is the small Pool of Azrael, associated with the underworld and used for sacred purposes. it is connected to the pool in the courtyard, and is possibly sourced from the White Spring.
Adorning the right wall are more of the daily candles. At the far end to the left is a door to the Shrine of Sheikh Hassan. Other doors lead to residential areas for religious leaders.
We were next ushered into the temple, which consists of an oblong apartment, divided into two aisles (that on the left being raised a few feet above the other) by a row of five arches, which support the roof. Badger 1852, p 106; of trips 1843-1850
To the right of the entrance is a platform, and a square basin of running water, with a seat at each corner, evidently intended for the accommodation of such as come here to bathe. Badger 1852, p 106; of trips 1843-1850
Along the wall to the right are several empty niches, and in the aisle opposite, stands a wooden tomb, covered with a curtain. Lower down the same aisle is a large recess, with a long Arabic inscription, which, to my astonishment, I found to be a quotation from the Koran. ... The quotation from the Koran near the tomb was also admitted by several Kawwâls to have been introduced as a blind, and in order to prevent the Moslems from desecrating their sacred shrine.
