The Kaaba is a sacred structure located in the center of the Masjid al-Haram in Mecca, Saudi Arabia. It is a cube-shaped building made of stone and is covered with a black silk cloth known as the Kiswah. Muslims around the world face the Kaaba during their daily prayers, making it the most important site in Islam. Every year, millions of Muslims travel to Mecca to perform the Hajj, a pilgrimage that includes circling the Kaaba seven times. The Kaaba is believed to have been built by the Prophet Ibrahim (Abraham) and his son Ismail (Ishmael), making it a significant symbol of faith and unity for Muslims.
