Oh look whose talking about the Quran, the same fool when quoted verses said which fool said this! LOL The same fool who was defending his fairytales which contradict the Quran
You know nothing about history. But thats nothing new you know nothing about nothing anyways
In pagan Arabia there were many Kaaba's and 5 well know Kaabas
The kaaba in mecca, in Najran, in Ghaiman, in sindad and Dhul Khalasa, the white kaaba.
The architectural style of the Meccan Kaaba is shared by a number of pre-Islamic buildings, which have broadly been labelled as Kaabas. They are primarily known from the Arabian Peninsula, but some have also been found in other regions, including the Kaaba of Zoroaster. The Black Stone of the Kaaba is similar to pre-Islamic cultic stones called baetyls, (Bait elah i,e house of god) which were often black, thought to be of meteorite origins, and venerated in houses or temples of worship for a particular deity. The other Kaabas also allegedly had their own counterparts of the Black Stone. There was a "Red Stone", in the Kaaba of the South Arabian city of Ghaiman; and the "White Stone" in the Kaaba of al-Abalat (near modern-day Tabala).
But to be honest I am on the fence of this issue. Purely because right now I have no interest in performing these mushrik practices of doing 7 rounds or throwing stones at concrete columns thinking they are the devil. Also Islamic historic sources say the kaabah wasn't originally this building, it was more of a rectangle and that this building has been destroyed and remade many times, people even stole the blackstone and smashed it, thats why its just tiny fragments set in concrete. And lets say even if it was the actual house of God, they have desecrated it with their mushrikness right on its gate.
TBH Hajj is one of the subjects I have done the least amount of research on, but enough to know that what passes of as hajj or umrah today has nothing to do with Islam.
