The excessively simple nature of the interior is in sharp contrast to the elaborate mehrab set into the south-western wall of the prayer chamber, which is one of the finest examples of Seljuk stucco work in the area. Surrounded by large angular Kufic in the same style as that on the uper part of the minaret behind it, the mehrab itself is full of intricately carved detail hiding amongst the muqqarnas or angular sections which transform the plain background wall into the arch which is projected from it.
The inscription surrounding the mehrab gives us the date on which it was completed and enunciates the five pillars of Sunni Islam (Shi'ites believe in seven). It can be translated as follows:
In the name of God the Compassionate the Merciful. Only they shall come into the mosque who believe in God, who believe in the Day of Judgement, who say their prayers, who give alms, and who fear only God. These will be on the path of righteousness. This [inscription] was completed in the month of God (i.e. Ramadan) Four hundred and ninety eight.
There is also a pair of inscriptions on either side of the mehrab which read "In the name of God the Compassionate, the Merciful" and "The All-hearing, the All-Seeing"

The dome has ribbed vaulting reminiscent of that used in the Dome of Nizam ul-Mulk in the Masjed-e-Jomeh, which in turn was said to derive from the wicker tents used by the nomadic tribes which first occupied Iran.
