Why is the cover of the Kaaba raised 3 meters above the ground before Hajj

The management of the Haram Sharifeen has raised the Kaaba 3 meters above the ground before the arrival of Hajj
The purpose of raising the cover of the Kaaba is to protect the cover from any damage during Hajj
In the past, pilgrims used to touch the cover of the Kaaba and cut pieces of it as a blessing, which damaged the cover
