The shrine building of Imam Hussain (A. S.)  was renewed for the fifth  time  by Adhud al-Dawla al-Buwaihi between 369  and 371 A. H. (980- 982 A. D. ).

He built over the tomb a lofty dome of clay brick and gypsum and added halls (rawaqs) around the building with a gate on each side.  He decorated  the interior of  the  shrine with red teakwood and surrounded the  hadhra  with a  large open courtyard  (yahan)  and this  was surrounded by  a  high wall with an entrance on each of  its four  sides.

Also, during the rule of the Adhud al-Dawla, the Amir of the Bata'ih in southern Iraq, Umran ibn Shaheen, built a mosque and another rawaq connected to the shrine in the western side of the hadhra and was later named after him.

It is now known as rawaq Sayed Ibrahim al-Mujab'.
