The minbar, situated on the right of the mihrab, is used by the imam during the Friday or Eids sermons, is a staircase-shaped pulpit with an upper seat, reached by eleven steps, and measuring 3.93 metres' length to 3.31 metres in height. Dated from the ninth century (about 862) and erected under the reign of the sixth Aghlabid ruler Abul Ibrahim (856–863), it is made in teak wood imported from India. Among all the pulpits of the Muslim world, it is certainly the oldest example of minbar still preserved today. Probably made by cabinetmakers of Kairouan (some researchers also refer to Baghdad), it consists of an assembly of more than 300 finely carved wood pieces with an exceptional ornamental wealth (vegetal and geometric patterns refer to the Umayyad and Abbasid models), among which about 90 rectangular panels carved with plenty of pine cones, grape leaves, thin and flexible stems, lanceolate fruits and various geometric shapes (squares, diamonds, stars, etc.). The upper edge of the minbar ramp is adorned with a rich and graceful vegetal decoration composed of alternately arranged foliated scrolls, each one containing a spread vine-leaf and a cluster of grapes. In the early twentieth century, the minbar had a painstaking restoration. Although it has existed for more than eleven centuries, all panels, with the exception of nine, are originals and are in a good state of conservation, the fineness of the execution of the minbar makes it a great masterpiece of Islamic wood carving referring to Paul Sebag. This old chair of the ninth century is still in its original location, next to the mihrab.
