Five other grand mosques were commissioned in Jeddah; the Suleiman mosque, the Harithy mosque, the Azizeyah mosque, the Jufalli mosque and the monumental King Saud Mosque. They were all in brick construction and provided an opportunity to develop traditional building crafts. The brick dome of the King Saud mosque with a diameter of 20 meters and a peak height of 40 meters challenged structural engineers who refused liability for its construction without concrete. El-Wakil signed an affidavit taking full responsibility for its structure. Being directly commissioned by King Fahd and promoted by the mayor of Jeddah, El-Wakil managed to circumvent all the bureaucratic regulations that would have prevented the mosque ever being built.
