A is considered as an absolute Islamic invention and a necessary religious idea as a stage which a speaker stands to perform his speech. Historic resources mentioned that a rostrum was introduced in mosques since the Prophet Mohammed (Peace and blessings be upon him) time in (7H/628G) when he was standing on atree-trunk and then they replaced it by a rostrum made from wood and equipped with two stairs and chair. After that in the age of Al-Rashidun Caliphs as it was developed into many kinds and shapes and mobile rostrums. In the Abbasid age , a kind of fixed rostrums were have been as that one in Abi Dalaf Mosque (245A.H/859A.G) which was made of bricks and chalk (kinde of limestone) and the rostrum of Al Amadiya Mosque (548/1153) which was made of woods. As for the city of Mosul in the Ottoman dynasty, the researchers divided that age into three eras: the time of Ottoman rulers , the time for local (Al Jalili rule) , as for third time which is point of this research , it was the time of this central administration which had been well-Known by the work of its men to seek the national independence. This seeking affected the city badly causing a recession in the architectural fields. However, those platforms embodies part of the legacy of Architecture, for that era, marked by the development of large it worked and marble-sized, as the the case with the rostrum Hamo Al-Qadu and Sheikh Abdal, so it was a matter of selection of these rostrums is not studied in a scientific integrated in terms of the investigating the scientific elements. It studies geometric element and and technical analysis whereas floral motifs and written inscription required archaeological studies, especially Islamic ones, as we will see in the pages of our search is.
