Mecca: The Mizab of the Holy Kaaba, known among Muslims as 'Mizab Al-Rahmah' or 'the Spout of Mercy', is one of the prominent architectural features associated with the Grand Mosque. It projects from the roof of the Holy Kaaba on its northern side overlooking Hijr Ismail (Al-Hateem), forming an important structural element within the components of the Kaaba's construction and combining a functional role with historical significance and spiritual symbolism.
According to Saudi Press Agency, the Mizab performs a fundamental function of draining rainwater that accumulates on the roof of the Holy Kaaba. It is designed with a calculated slope that allows water to flow toward Hijr Ismail, where those performing Tawaf (circumambulation) pause to supplicate and pray, particularly when rain pours from the spout, in a devotional scene that combines the site's architecture with its spiritual character.
The Mizab is distinguished by precise geometric dimensions. It measures about 2.53 meters in length and approximately 26 centimeters in width, while the height of its two sides reaches around 23 centimeters. Its outer end - projecting beyond the wall of the Kaaba - extends roughly 58 centimeters, allowing water to flow away from the wall directly toward Hijr Ismail.
Moreover, the Mizab is made of 24-carat pure gold, with the gold used in its construction weighing about 50 kilograms. It is mounted on a sturdy internal metal base that secures it firmly at the top of the Holy Kaaba's wall. The interior is also reinforced with supporting metal layers to ensure durability and resistance to various weather conditions, while preserving its original architectural form.
The Mizab is distinguished by intricate Islamic ornamentation executed in harmonious geometric and vegetal motifs, alongside Arabic inscriptions that adorn its sides. These decorations reflect the aesthetics of Islamic art and the precision of the craftsmanship with which it was made. Its current form represents a continuation of the architectural design preserved through the renovation and restoration works carried out on the Holy Kaaba over time.
The Mizab has undergone successive renovation and maintenance works to preserve its safety and structural function. It was renewed during the Saudi era as part of restoration works on the Holy Kaaba, while maintaining its historic form and using high-quality materials and precise techniques in its manufacture and installation. The government of Saudi Arabia devotes significant care to the Holy Kaaba and its components, including Mizab Al-Rahmah, which are subject to periodic maintenance and inspection programs supervised by specialized authorities to ensure their structural integrity and preserve their architectural appearance, as part of an integrated system serving the Grand Mosque and its visitors.
Today, the Mizab of the Holy Kaaba stands as one of the distinctive architectural testimonies bearing the weight of history. It remains present in the memory of those performing Tawaf and visitors to the Grand Mosque, bearing witness to the history of the construction of the Grand Mosque and to the meticulous care given by the government of Saudi Arabia to the two holy mosques, in order to preserve their sanctity and ensure the continuity of their enduring message through the ages.
