In the year 1771, Mohamed Abu Al Dahab was appointed by Amir Ali Beh Al Kabir to be the leader of the Egyptian army that went to conquer Syria. He was successful in his campaign as he took control of many towns in Syria and around it. However, Mohamed Abu Al Dahab was not loyal to his master, Amir Ali Beh Al Kabir, and murdered him in 1774, and became the only ruler of Egypt before his death in Aka in 1775. His body buried in the mausoleum of his mosque.
The Mosque of Abu Dahab is located in the Azhar Street, just beside the main entrance of the Azhar Mosque. It was built in 1774 AD after a year of construction. It was originally built as a Madrasa to host the increasing number of students that were coming to study in the Azhar University from all over the world.
The mosque is considered the fourth mosque to be built in Cairo according to the Ottoman style of architecture. The first one was the mosque of Suleiman Pasha in the Citadel built in the year 1528. The second one was the mosque of Sinan Pasha in Boulaq, while the third was the Mosque of the Queen Safeya in Al Dawedeya. The mosque of Abu Al Dahab has many common architectural factors with the mosque Of Sinan Pasha.
The mosque is constructed as a rectangle with the length of 33 meters from the South to the North and 24 meters from the East to the West. The praying area of the mosque is surrounded with Rewaqs, the Arabic expression for the area between a set of two opposite pillars. These Rewaqs are covered with small domes with plant decorations all around them.
Above the praying area, there is the main dome of the mosque that is a semi square. The length of each side of this square is 15 meters and each has two brass windows that are covered with alabaster.
The mosque of Abu Al Dahab is considered a hanging mosque as it was built above the street level. Under the mosque from the Eastern and Northern sides, there are many different stores that mainly sell books. There was a set of colored alabaster stairs in its Northern side that led to the gate of the mosque, and another set circular stairs that led to the Mosques Eastern gate. These two sets of stairs were changed, although the doors of the mosque remained the same.
The minaret of the mosque is huge and looks much like the minaret of the mosque of Qonswa Al Ghuri. They both share the Egyptian style of architecture other than the Ottoman Mosques that were famous for their thin pen shaped minarets. The minaret of the mosque of Abu Al Dahab is tall consisting of three stores with five stone heads at the top.
The Mihrab of the mosque is located under the main dome of the mosque. It is a carved wall that has beautiful alabaster and mother of pearl decorations. The Mihrab of this mosque is unique, being built in the Ottoman period, as it designed in the Mamluks style.
