The Prophet's System and the Ka'aba

At the time of the Prophet's system, it was just a long square structure. The Benu Abdi Manaf did this, the process of self-tribe. They made the door of the Ka'aba in the middle of the wall not on the ground where people could go in. And to this day, the door is high because of that. Then they built a water spout Because what happened before, the roof caved in due to rain and flood.
