Six construction of Imam Hussain Holy Shrine

Fire broke out in the holy shrine during the reign of Adud al-Dawla the Buyid, burning the dome and courtyard.
Hassan B. Mufaddhal renovated the building in 412 A.H. He built a dome on the shrine renovating what the fre had
destroyed. He also gave the ordered to surround the shrine with a high wall which, later, was mentioned by Ibn Idrees
in his book (al-Serair). In 588 A.H. Ibn Sehlan renewed the outer wall to increase durability.
