The traditional belief is that the Kaaba is approximately 5000 years old, having been built by Abraham.
Before it became the central focus of Islamic prayer, as instructed in the Quran, the Kaaba was a pagan religious building. It housed numerous statues representing various pagan deities. This predates its significance in Islam and provides context for its age. The estimated age of 5000 years reflects the period when Abraham is believed to have built or rebuilt the structure.
