The area for nocturnal prayers in the southern section has sixteen round pillars in the center and eight and a half columns towards the eastern wall which form the pillars of the ceiling in this vicinity. This portion was constructed during the times of Arqoon Khan, under the supervision of his minister Sheikh Alaoddoleh Semnani.
The same was repaired during the reign of Fathali Shah Qajar under the orders of Zulfaqar Semnani. To the south east of this area is the Saljuqi minaret, currently rising to the height of 31.20 m. and with a circumference of 5.5 m. On the top of this minaret is an inscription affixed on the intricate brick work, showing the date of construction. The crown of the minaret is octagonal, with arches in brick works, in addition to the blue tiles. The area where the 'Azan' or the call for prayer is read is railed off with a beautiful wooden latticed worked railing.
