Brother what you call "been practiced for centuries" could have been cooked up only a hundred some years ago. The way history was and still being written, we don't even know what was happening with anything under the reigns of the kings/khudaas of the world.
I was surprised to see the pictures of Kaba in 19th century, only a hundred plus years ago. How come the kaba THEN when indeed there were hundreds of Muslim made beautiful and grandeur architect, be in such bad form? The kaba then was no way the kaba we see now. And it could not have been that they could not make it into something presentable.
That got me thinking if the history we were told and the religion we were following the same as it was given to us by the Prophet SW!
I hope they don’t change the pictures now that the thing is out.
