RIYADH: Periodic maintenance of the Kaaba and the perfuming of its Kiswa was carried out on Monday ahead of the last ten days of Ramadan. The last ten days of the holy month start on Tuesday and Muslims intensify their worship during this period in search of Laylat Al-Qadr, the holiest night of the Islamic calendar. Laylat Al-Qadr marks the night when the Qur’an was first revealed to Prophet Muhammad and is believed to have taken place on one of the final 10 nights of Ramadan, though the exact night is unclear. Sheikh Abdulrahman Al-Sudais, the president of the General Presidency for the Affairs of the Two Holy Mosques, oversaw the maintenance and said that the Saudi leadership is keen to take great care of the Kaaba due to its Islamic significance. He added that the presidency uses the best types of perfume to fragrance the Kaaba and the finest silk to make its Kiswa.
