“Somebody kissed my foot in a DREAM, I said I am the black stone
Ahmad(As)said that I am that Hajar-i-Asward that has been accepted on this earth by the people and is touched by them for blessings (Istifta pg 41)
In the footnote Ahmad(As) states that the interpreters of dreams say that the black stone in a DREAM means a scholar, a jurist, and an earned man.
The Holy Prophet(Saw) said to Ali that O Ali, you are like the Ka’ba. Such are not to be taken literal rather metaphorical and this was a dream so your allegation is baseless just like the rest
