What is the ruling on touching the walls of the Ka'bah?

Question:
This questioner asks: What is the response to those who insist on touching the walls of the Ka'bah, and who cite as evidence for this the statement of the Companion Mu'awiyah (may Allah be pleased with him) that nothing of the House is neglected?

Answer:
Oh, the glory of Allah! They did not complete the report; they took what suits them and left what does not suit them. Mu'awiyah (may Allah be pleased with him) used to touch the four corners, so Ibn 'Abbas said to him: The Messenger (peace and blessings be upon him) did not touch anything except the Yemeni Corner and the Black Stone. Mu'awiyah (may Allah be pleased with him) said: Nothing of the House is neglected. Ibn 'Abbas (may Allah be pleased with him) said to him: . Mu'awiyah (may Allah be pleased with him) said: You have spoken the truth, and he retracted this statement. Mu'awiyah retracted this and said: You have spoken the truth, . Yes.
