Authorities in Saudi Arabia say more than two million pilgrims performed Qiyam al-Layli at the Grand Mosque.
Pilgrims and other Muslims are expected to perform Laylat al-Qadri on such nights as the Night of the Unknown - 21, 23, 25, 27, and 29.
Thousands of Muslims have entered Saudi Arabia this year to perform 'Umrah, after the country relaxed its corona rules.
