The story of Ali's birth in rukne yamani

Fatimah binte asad, the mother of Ali, was in labour pains. She went up to the Kaaba and said:

"Oh God, I have firm faith in you, the prophets, the books sent down by you, and the speech of my grandfather- the builder of this house. Oh God, for the sake of this child in my womb, make the birth of this child easy." An instant later, the south-east wall of the kaaba opened. Fatimah binte asad entered this crack and the crack then closed.She was the guest of Allah for 3 days in the holiest ever place and then gave birth to her child- Ali. This was on the 13th Rajab. She came out of the kaaba and Mohammad met her and said: "I heard a message from the unseen to call him Ali."

This crack in the kaaba is still there on this very day.
