The Umayyad Mosque - The Islamic Cities (sitios de interés)
Descripción del sitio
The first mosque ever in the city, built in 640 A.D. by Utba bin Farqad Al-Salami after he conquered Mosul in the reign of Caliph Omar ibn Al-Khattab.NOTE: This directly contradicts many other sources that I used in writing my paper that put Mosul's establishment (as a misr even) at 641 A.D. Looking at sources now, it seems the majority of them say that Utba bin Farqad Al-Salami conquered Mosul in 637 A.D. Regardless, it seems that this was certainly the first mosque in the region, and it must have been built soon after the misr had been established and the Kufans settled. The date of the building of this mosque seems appropriate: around 640/41 A.D.
The only part still extant is the remarkably elaborate brickwork 52 m high minaret that leans like the Tower of Pisa, called Al-Hadba (The Humped). The original mosque was most likely used primarily for Friday prayer services by the settled Kufans. SEE NOTE BELOW!
(Note: This seems to be incorrect information regarding the location of the remains of this mosque. Where the remains actually are is still up in the air, but I've found a definitive source that contradicts this assertion. Bottom line is that this humped minaret is NOT part of the Umayyad Mosque from 640 A.D. See the placemarker for al-Nuri Mosque).
