Dear Imam Salaam Alikum, You know anyone could write history, but it is not necessarily true. In the same token the birth of Imran Ali cannot be inside the Kaba, because when he born there were 360 idols inside the house, and When he opened his eyes, That would be the first thing he would see , so no he did not born inside the house which all of the Sheia believe……..
It is proven from Sahih hadith that Imam Ali was born in the Kaabah and the first thing he opened his eyes to were the prophet ﷺ. Why does it hurt you so much that Allah blessed Imam Ali with this? This isn’t a Shia belief, but your statement is one of nasibism
