The 13th of the month of Rajab, twenty-three years before the migration of the Prophet Mohammad (pbuh) a child was born in the family of Abu Talib, the light of whom kindled the whole World. Kunaab Mecci narrates about his birth: "We and Abbas (Ibne Abdul Mutalib) were sitting together when suddenly we saw Fatima bint-e-Asad moving towards the Kaba in the condition having delivery pain and saying "Oh God I have faith in you and the Prophet (i.e., Abraham) who by your command laid the foundation of this house. O God! I swear you by the same Prophet Mohammad (pbuh) and swear you by the child in my womb make this birth comfortable and easy for me."
This was the time when all of us saw with our own eyes that the wall of Kaba broke apart and Fatima bint-e-Asad entered into the Kaba. Then the wall again united.
We ran terrified and trembling to our houses to send our women into the Kaba for the help and assistance of Fatima bint-e-Asad. We did our best but the door did not open. This event surprised all the people of Meccah.
The women of Macca were anxiously counting moments to meet Fatima bint-e-Asad till the time she came out of the Kaba along with a beautiful baby, saying, "God has chosen me from among the ladies of Macca and He made me His guest in His house and gave me meals and fruits of the heaven to eat.
The ladies who were surrounding her in the form of a circle and escorting her to her home asked her, "What name have you given to this child?" Fatima bint-e-Asad said: "When I was in the Kaba, I heard a hidden voice call," Name this child "ALI".
Yes! We are talking about Imam Ali ibn Abu Talib (AS) the pious man whose childhood and infancy period lasted in such a pure and chaste way that he himself stated in Nahjul Balagha, "The Prophet Mohammad (pbuh) used to pick me in his lap and embrace me and chew the food and put it into my mouth."
