The procedure is meant to keep the cover, known as kiswa, free from getting soiled and tampered with as pilgrims performing Hajj circumabulate the Kaaba RIYADH: In keeping with the annual tradition, officials raised the lower part of the kiswa — the elaborately designed black cloth covering the Kaaba — in Makkah on Wednesday ahead of this year"s Hajj pilgrimage. As approved by the General Authority for the Care of the Affairs of the Two Holy Mosques, the exposed part was covered with a white cotton fabric, two-and-a-half meters wide and 54 meters long on all four sides, according to the Saudi Press Agency. Carrying out the procedure were 36 specialized technical personnel with the aid of 10 cranes. As described in the SPA report, the kiswa is lifted in several stages: It starts with unscrewing the bottom of the cover from all sides, separating the corners, then untying the bottom rope and removing it from the fixing rings, after which the cloth is rolled upward. The lanterns are then dismantled and the white cloth are put in place, after which the lanterns are reinstalled over the white cloth until the final stage. The procedure is repeated every year to protect the kiswa from getting soiled and damaged as pilgrims circumambulate the Kaaba. The annual Hajj in Saudi Arabia is considered the world"s largest human gathering, with year 2012 marking the biggest number of participants at 3.16 million. At the height of the COVID-19 pandemic, Saudi authorities allowed only a symbolic observance of Hajj with just a thousand pilgrims. The numbers were gradually raised as the health crisis was placed under control worldwide. Last year, almost 1.84 million pilgrims performed the "once in a lifetime" journey and the figure is expected to go higher this year. Every year, on the ninth day of the Islamic month of Dul Hijjah, the black silk cloth is removed and a new kiswa is draped in its place.
