Top of the minber. Minber = a pulpit in the mosque where the imam (prayer leader) stands to deliver sermons.
The presence of a minber is essential for an Islamic house of prayer to be called ‘cami’ (= Friday mosque). In the absence of a minber, the house of prayer is unfit for the solemn Friday prayer and is called ‘mescit’ (= small mosque).
