Final answer:
Imam al-Mu'izz planned the construction of the city of Al-Qahira (Cairo) in the 10th century.
Step-by-step explanation:
The construction of the city of Al-Qahira, also known as Cairo, was planned by Imam al-Mu'izz. Although we do not have the name of someone considered an "architect," we know that the "supervisor of construction" was an emir named Muhammad Ibn Baylik al-Muhsini, whose name is inscribed on a text band on the interior of the mosque. The city was built in the 10th century and is known for its architectural landmarks such as the madrasa and Friday Mosque of Sultan Hasan.
