Further to my post about the eastern city, Dammam, Qateef, Al Ahsa and stealing of black stone from kaba, it is said that Taher Qarmati personally lead the attack on Kaba and took the Stone with him.
In Qateef there is still some Archeological remains of the place where they buil the kaba and place the black stone.
It would be a news for most of the readers that the hajr e aswad was away from the kaba for more than 29 years.
Qarmati's history is dated back to Ismaili Nizari rulers whole empire was in bahrain, qatar and some part of UAE.
There is number of sites in Arabic language regarding the history of qarmati but for the english readers this link will be a sort of help http://en.wikipedia.org/wiki/Qarmatians
