Answer
Mecca, the holiest city in Islam, was conquered in late 692 by Abd al-Malik's general, al-Hajjaj ibn Yusuf. This conquest marked a significant victory for the Umayyad dynasty, as Mecca had been a stronghold of opposition to their rule. Al-Hajjaj's conquest brought the city under Umayyad control and solidified their authority over the Arabian Peninsula.
