The Ruling on Rubbing the Walls of the Ka'bah

Question:
May Allah reward you. Honorable Shaykh, regarding rubbing the Ka'bah or the wall of the Ka'bah, he asks: What is the ruling on it?

Answer:
One does not rub any part of the Ka'bah except the Yemeni Corner and the Black Stone, and one kisses it if possible. The other corners and the walls of the Ka'bah are not to be rubbed, as there is no evidence for this. The obligatory act is to perform tawaf (circumambulation) of the Ka'bah and to pray facing it. This is the obligation. Yes.
