In 767 A. H. (1366 A. D. ), Aminul Din Maijan, the  governor  (wali) of  Baghdad appointed by Sultan Uwais, built  a minaret which was later known as Nfi'thanat  al- Abd (the minaret of the  slave). This was  built  of local clay brick (ajur), and gypsum and was situated in  the eastern side of the  open courtyard of  the  shrine of Imam Hussain (A. S. ). He also built a small mosque next to it.

Repairs, improvements and additions were made to the shrine building in different pedods, especially during the rules of the Safavids, Ottomans and Qajaris. In 914 A. H. (1508 A. D. ), Shah Ismail al-Safavi offered a gift consisting of a raised chest with latticed window on four  sides,  known as al-dharih,  designed  with silver and erected above the grave of  Imam Hussain (A. S. ). He also ordered the gilding of the borders around the exterior of this al-dharih. This was the first time gold was used in decorating these buildings.

In 948 A. H. (1576 A. D. ), following instructions from the  Ottoman Sullan Murad (III),  the Ottoman wali (governor), Ali Pasha al-Wendzada, renewed the building of  the  mosque (i.e. the shrine) of Imam Hussain (A. S. )  and its illuminated dome.

In 1048 A. H. (1638 A. D.), the Ottoman Sultan, Murad (IV), ordered the restoration of the dome of the  shrine of  Imam Hussain (A. S. ). It was built of clay brick (ayur) and gypsum and then plastered from the outside with gypsum.
