Assalamu alaykum.
First of all Id like to apologize for not providing any evidence or link to this questin as I saw the video a long time ago
So I came across tthis video on youtube that said Mecca, the Kaaba the Black stone were all Hindu once upon a time. Meaning that the Prophet changed that religion into modern day Islam. They show some "similarities" between the two faiths such as the growth of the beard etc. Historically this is ridiculous and has no basis. But whats your opinion, are their arguments genuine, do they weigh anything?
