Mizab Al Rahmah: Saudi Era Maintenance Preserves Holy Kaaba's Architectural Significance
The Mizab of the Holy Kaaba, known as "Mizab Al-Rahmah" or "the Spout of Mercy," is a key feature of the Grand Mosque’s architecture. It combines a clear practical purpose with deep religious meaning, linking the structure of the Holy Kaaba to worshippers’ experience around it.
The Mizab directs rainwater from the roof of the Holy Kaaba toward Hijr Ismail (Al-Hateem), where many pilgrims stand in prayer. During rainfall, people performing Tawaf often stop beneath the spout and raise their hands, creating a devotional scene closely tied to this specific architectural element.

Located on the northern side of the Holy Kaaba, the Mizab projects outward above Hijr Ismail. It is built with a precise incline so water runs smoothly away from the roof. The flow is carefully directed beyond the wall of the Kaaba and toward the Hijr area, helping protect the structure.
The visible section of the Mizab extends about 58 centimetres beyond the Kaaba’s wall, which keeps water from streaming down the masonry. This measured distance helps preserve the external surfaces and supports safe drainage while keeping the link between the spout and the worship space beneath it.
The Mizab is built with strict geometric measurements. Its length is around 2.53 metres, while its width is approximately 26 centimetres. The height of the two side walls is about 23 centimetres, forming a channel that guides water efficiently from the roof toward the designated area below.
The structure is manufactured from 24-carat pure gold, with the total gold used weighing close to 50 kilograms. Beneath the visible gold exterior, a strong metal base anchors the Mizab at the top of the Holy Kaaba’s wall. Internal metal layers add support and help it withstand different weather conditions.
Mizab of the Holy Kaaba ornamentation, history and care in the Grand Mosque
The outer surfaces of Mizab Al-Rahmah display detailed Islamic decoration, including balanced geometric shapes and plant-inspired motifs. Arabic inscriptions appear along its sides, reflecting the traditions of Islamic art. The current form continues a design approach preserved through various restoration projects on the Holy Kaaba across different periods.
The Mizab has been renewed several times to maintain its safety and purpose. During the Saudi era, it was replaced and restored as part of broader work on the Holy Kaaba. Specialists used high-quality materials and accurate methods so the updated spout kept its earlier appearance while gaining stronger structural reliability.
The government of Saudi Arabia gives particular attention to the Holy Kaaba and its elements, including Mizab Al-Rahmah. Regular inspection and maintenance programmes are run by specialised bodies. These efforts form part of an integrated system that aims to protect the structure of the Grand Mosque and serve its millions of visitors.
Today, the Mizab of the Holy Kaaba remains a familiar landmark for pilgrims performing Tawaf and other visitors to the Grand Mosque. It reflects both the long history of the mosque’s construction and the continuing care given by Saudi Arabia to the two holy mosques, ensuring their sanctity and ongoing religious role.
