Inside the Kaaba, the interior is quite simple and sparse, reflecting its sacred nature rather than being a place of elaborate decoration or ritual. The main features inside the Kaaba include:
- Three wooden pillars that support the roof.
- A small altar or table situated between the pillars.
- Several hanging lamps and incense burners, some made of gold and silver, gifted by various Islamic rulers over time.
- The floor is made of marble and limestone, with the interior walls clad in white marble up to about halfway to the roof, and darker trimmings along the floor.
- The walls are adorned with inscriptions and Quranic verses embroidered on cloth that covers the upper parts of the walls and ceiling.
- There is a staircase inside that leads to the roof, accessible through a golden door called the "Door of Repentance" (Bāb al-Tawbah), which is opened only on rare occasions for maintenance and ceremonial cleaning.
- The interior space is about 180 square meters, polygonal in shape due to the stairwell.
The Kaaba interior is not open to the general public; only select dignitaries, religious scholars, and maintenance workers are allowed inside, mainly for cleaning and upkeep purposes. The inside is devoid of treasures or relics, emphasizing its role as a sacred space symbolizing the unity of Muslims in prayer rather than a site for display
. In summary, the Kaaba's interior contains:
- Three wooden pillars
- A small altar or table
- Hanging lamps and incense burners
- Marble floors and walls with inscriptions
- A staircase to the roof behind a locked golden door
No treasures or relics are kept inside; it is a simple, revered space central to Islamic worship.
