The Kaaba was built by Prophet Ibrahim and his son Ismail as the first house of worship dedicated to the One God. The Quran states: 'Indeed, the first House established for mankind was that at Bakkah — blessed and a guidance for the worlds' (3:96). It has been rebuilt multiple times, with the current structure dating to 1629 CE under Ottoman Sultan Murad IV.
According to Islamic tradition, Allah commanded Prophet Ibrahim (Abraham) and his son Ismail (Ishmael) to build the Kaaba as the first house of worship dedicated solely to the One God. The Quran records their prayer during construction: 'Our Lord, accept this from us. Indeed, You are the Hearing, the Knowing' (2:127). Some scholars narrate that the original foundations predated Ibrahim, having been laid by angels or by Adam, and that Ibrahim raised and rebuilt the structure. The Kaaba in its Ibrahimic form was a simple rectangular structure oriented on its current axis, with a door at ground level and an interior slightly below ground. The Hijr Ismail (the semi-circular area adjacent to the northern wall) was part of the original structure but was later excluded during the Quraysh rebuilding due to insufficient funds.
Over the centuries following Ibrahim, the monotheistic worship at the Kaaba gradually gave way to polytheism. By the time of Prophet Muhammad (peace be upon him), the Kaaba housed 360 idols. Despite this corruption, the Kaaba retained its central importance in Arabian religious and commercial life, and certain Ibrahimic practices — including pilgrimage and circumambulation — continued in modified forms. In 605 CE, when Muhammad was approximately 35 years old, the Quraysh rebuilt the Kaaba after flood damage. Due to insufficient pure (halal) funds, they made it smaller than Ibrahim's original dimensions, excluding the area now known as the Hijr. They also raised the door above ground level to control entry. The famous incident of the young Muhammad resolving a dispute over who should place the Black Stone in the rebuilt wall — by placing it on a cloth that representatives of each clan lifted together — is well documented in the seerah.
The Kaaba has been rebuilt or extensively renovated several times since the Prophet's era. In 683 CE, Abdullah ibn al-Zubayr rebuilt the Kaaba on Ibrahim's original dimensions during his caliphate in Makkah, adding a second door and incorporating the Hijr area. After the Umayyad reconquest in 692 CE, Caliph Abdul Malik ibn Marwan restored it to the Quraysh dimensions. When the Abbasid Caliph Harun al-Rashid considered returning to Ibrahim's dimensions, Imam Malik advised against it to prevent the Kaaba from becoming a political instrument rebuilt by each successive ruler. Major flood damage in 1629 CE necessitated a near-complete rebuild under Ottoman Sultan Murad IV, producing the structure that largely stands today.
The current Kaaba stands approximately 15 meters tall, 12 meters long, and 10 meters wide. Its walls are constructed from granite blocks quarried from the hills near Makkah. The interior floor and lower walls are clad in marble. The Black Stone (Hajar al-Aswad) is set in the eastern corner at approximately chest height. The door, made of pure gold, is on the northeastern wall approximately 2.13 meters above ground level. The Kaaba is draped in the Kiswa, a black silk cloth embroidered with gold Quranic calligraphy, which is replaced annually. The Kiswa production facility in Makkah uses approximately 670 kilograms of raw silk, 120 kilograms of gold thread, and 100 kilograms of silver thread for each year's covering.
The Kaaba serves as the qiblah — the direction of prayer — for over 1.8 billion Muslims worldwide. Five times daily, from every point on earth, Muslims orient themselves toward this single structure in prayer. The Kaaba is also the center of Tawaf, the ritual circumambulation performed during Hajj and Umrah. Muslims are careful to emphasize that the Kaaba itself is not worshipped — it is a direction and a symbol, not an object of devotion. The worship is directed to Allah alone, and the Kaaba serves as the physical focal point that unifies the global Muslim community in a single direction of prayer. The Quran commands: 'So turn your face toward al-Masjid al-Haram. And wherever you are, turn your faces toward it' (2:144).
