What is valid and what is not valid in facing the Black Stone

Question:
Does one face the stone with every ......?

Answer:
He faces it, he turns toward the stone and touches it if it is easy to do so. If he turns his side toward it and touches it, there is nothing wrong with that; the matter is broad.
Q: Adding "In the name of Allah"?
A: Ibn 'Umar (may Allah be pleased with him) used to do it: saying "Bismillah, Allahu Akbar." The matter is broad; I do not know of anything authentic and established. It is only from the action of Ibn 'Umar.
Q: In all the circuits or only in the first one?
A: In all the circuits, the first and the last, up to the final circuit. Whenever he aligns with it, he says the takbir and then finishes.
Q: Is prostration on the stone mentioned in this regard?
A: Prostration on the stone is mentioned in some hadiths. There is no harm in it. There are reports traced to the Prophet and reports stopping at Ibn 'Abbas, but the established hadiths mention kissing. Kissing is sufficient.
Q: Is the recitation of the name in the first circuit from the action of Ibn 'Umar?
A: Yes, Ibn 'Umar used to do it, and it appears that he did it at every circuit. As for the established hadiths, they mention the takbir.
