The full moon appeared just above the Kaaba last night, the first full moon above the Kaaba this year.
A few days ago, a Saudi newspaper reported that this would be the first time on January 28, 2021 that the full moon would be above the Kaaba.
The fact that the moon and the sun are visible directly above the Ka’bah makes it easier to determine the direction of the Qibla. In the past, the direction of the Ka’bah was determined in the same way.
