Was Hazrat Ali (RA) born inside the kabba with the walls cracked?

I heard that Imam Ali (May Allah be pleased with him) was born inside the Ka'bah, **that is the walls cracked** and he was delivered inside the kaabah. My question is what is the validity of this story according to **the Shia**? Did the events in this story actually happen? I am looking for clear cut evidences of the veracity of this story and the events in it according to the Shia view.
