Al-Hussein Mosque

The al-Hussein Mosque or al-Husayn Mosque, also known as the Mosque of al-Imam al-Husayn (Arabic: مسجد الإمام ٱلحُسين) and the Mosque of Sayyidna al-Husayn, is a mosque and mausoleum of Husayn ibn Ali, originally built in 1154, and then later reconstructed in 1874. The mosque is located in Cairo, Egypt, near the Khan El-Khalili bazaar, near-by the famous Al Azhar Mosque, in an area known as Al-Hussain. It is considered to be one of the holiest Islamic sites in Egypt. Some Shias believe that Husayn's head (ra's mubarak) is buried on the grounds of the mosque where a shrine currently stands.
According to Fatimid tradition, in the year 985, the fifth Fatimid caliph, al-Aziz Billah, located the site of his great-grandfather's head through the office of a contemporary in Baghdad. It remained buried in the Shrine of Husayn's Head in Palestine for approximately 250 years, until 1153. It was "rediscovered" in 1091 at a time when Badr al-Jamali, the vizier and de facto regent under Caliph al-Mustansir, had just reconquered the region for the Fatimid Caliphate. Upon his order, the construction of a new Friday mosque and mashhad (memorial shrine) was initiated at the site.
Due to the advance of the Crusaders, Caliph al-Zafir ordered the transfer of the head to Cairo. Husayn's casket was unearthed and moved from Ashkelon to Cairo on Sunday 8 Jumada al-Thani, 548 (31 August 1153).
According to historians al-Maqrizi, Ahmad al-Qalqashandi, and Ibn Muyassar, the casket reached Cairo on Tuesday 10 Jumada al-Thani (2 September 1153). Taken by boat to the Kafuri (Garden), the casket was buried there in a place called Qubbat al-Daylam or Turbat al Zafr'an (currently known as al-Mashhad al-Hussaini or B'ab Mukhallaf'at al-Rasul). All Fatimid Imam-Caliphs, from Abdullah Al Mahdi to Al-Amir bi-Ahkami l-Lah, were buried at Turbah al-Zafaran, in the vicinity of the mosque and of the main Fatimid Palaces.
The vizier Tala'i ibn Ruzzik subsequently intended for the head to be moved to a new mosque and shrine he purposely built in 1160 (the Mosque of al-Salih Tala'i, south of Bab Zuwayla), but this transfer never occurred.
The building was reconstructed under the Ayyubids in 1237 and was burned down 11 years later. The Ayyubid minaret above the Bal al-Akhdar gate is the only part of the Ayyubid mosque that survives today.
Regarding one of the "custodians" who brought Husayn's casket to Cairo, the famous Mamluk historian of Egypt, Mohiyuddin Abd al-Zahir, wrote:
To mark the site of burial, known as Ra's al-Husayn (Arabic: رَأس ٱلحُسَين) or Mashhad Ra's al-Husayn, Taher Saifuddin had a zarih built in Mumbai, which was later installed at the mosque in 1965 just before his death. It was subsequently inaugurated by his son, Mohammed Burhanuddin.
According to tradition: The zarih was originally meant for Al Abbas Mosque, in Karbala, Iraq but could not be installed there: The location and the zarih had previously been measured precisely, but it simply didn't fit. Taher Saifuddin, the maker of the zarih, received divine guidance by way of intuition that out of loyalty, Al-Abbas ibn Ali—who was martyred along with his half-brother, Husayn, at the Battle of Karbala—could not allow Ra's al-Husayn be without a zarih. As a consequence, Al-Abbas' zarih was flown to Cairo and installed at Ra's al-Husayn at the Al-Hussein mosque, instead.
The Mosque was severely damaged by water and was restored by the Supreme Council of Antiquities in 1996. Major restoration was done to the tomb chamber, during which a replacement dome made of steel was placed over it.
There were further extensive renovations done in March 2022 which included a new shrine. The mosque was then inaugurated by President Abdel-Fattah El-Sisi and 53rd Da'i al-Mutlaq of Dawoodi Bohras, Mufaddal Saifuddin in April 2022.
The building of the mausoleum was completed in 1154. Of this original Fatimid architectural structure, only the lower part of the south side gate called Bab Al-Akhdar remains original in the mosque today. A couple years later, a minaret was added to the original Fatimid gateway by the Ayyubids in 1237. The minaret has panel carvings of overlapping lines that create patterns called arabesque popular in Islamic Architecture. The different minarets among this mosque play a role in portraying the various powers that ruled Cairo and the way they laminated their power through architecture. Finally in 1874, Isma'il Pasha (Khedive Isma'il) reconstructed Al-Hussein mosque inspired by the Gothic Revival Architecture. Wanting to modernize Cairo, Isma'il Pasha created a mosque with Italian Gothic style and Ottoman style minarets. This mixture of various architectural styles famous in Islamic architecture during the khedival time period is called Islamic eclecticism.
Today, the latest addition to Al-Hussein Mosque are three large canopy umbrellas. It was added to protect those praying outdoors from the sun during the summer days and from the rain during the winter. They are mechanically operated and follow the designs of those at many Saudi Arabian mosques made from steel and teflon. Many people still come to this mosque to pray and visit the mausoleum on a normal basis. Although non-Muslims are not allowed into the building, the structure is still viewed from the outside by tourists.
Next to Ras al-Husayn is a crypt, housing artifacts believed to belong to Muhammad. A door laden with silver and gold was built by Mohammed Burhanuddin II and installed at the site in 1986.
The room was added to the mosque in 1893. The room contains a piece of cloth believed to be part of a linen cloak once worn by the prophet, a lantern with four strands of the prophet's hair inside it, kohl made of copper also belonging to the prophet, staff of the prophet with which he entered Mecca as a conquest and a sword that was sent to him by one of his companions. Furthermore, it includes a copy of the Quran written by Ali ibn Abi Talib written in Kufic script, containing 501 pages and written on deer skin.
