What is the evidence for pointing at the Black Stone with the right hand only, as opposed to the evidence that necessitates raising both hands?

Scholars differed regarding pointing to the Black Stone when unable to touch it. The Malikis were of the opinion that one should not point, but suffice with saying "Allahu Akbar" and moving on. The majority, however, held that pointing is recommended.

Those who advocated pointing differed on how it should be done: - The Shafi'is and Hanbalis held that one should point with the right hand only, citing the Hadith of Ibn Abbas, in which the Prophet, peace and blessings be upon him, pointed with something in his hand. They also reasoned by analogy to touching, which is done with the right hand, and that the right hand is preferred in acts of worship. - The Hanafis held that one should point with both hands, similar to the takbir for beginning prayer (takbirat al-ihram). They based this on the saying of Ibrahim al-Nakha'i and a marfu' hadith attributed to the Prophet, peace and blessings be upon him. However, the saying of a Tabi'i is not a proof against others, and the marfu' hadith is weak and does not contain mention of pointing at the Black Stone.
