On Friday, the 13th of the blessed month of Rajab, 12 years before the mission of Holy Prophet Muhammad (S.A.W.) as Allah's Messenger, Fatima, daughter of Asad, felt that she was about to give birth to her child. Abu-Talib brought her to the Sacred Ka'aba in Makkah and let her enter and told her to sit down, then he went out. She raised her hands in prayer to beseeching Allah, the Most High, saying: "O Allah! I believe in You and in the messengers and the scriptures You have sent. I believe in what has been said by my grandfather, Abraham (A.S.) who built the Ancient House (the Ka'aba). So, for the sake of the builder of this House, and for the sake of the child in my womb, I implore You to make my labor easy."
Fatima stayed not more than an hour inside the Ka'aba when she announced that she gave birth to a male child. This child is the first child born in the Sacred Ka'ba.
No one before or after him has ever been born in the House of Allah, the Most High. It is a mark of him being honoured by Allah, the Most High, may his name be exalted, and of his position being dignified in its progress. Glad tidings were brought to Abu-Talib and his household. They hurried there while happiness spread over their faces.
Muhammad Mustafa (the chosen) proceeded among them and took the child in his anxious arms. He carried the baby, Ali, to the house of Abu-Talib because the Messenger of Allah (S.A.W.) was living at that time with his wife, Khadija, in their own house since their marriage.
It came to Abu-Talib's mind to name his new born child "Ali" and thus it was.
Abu-Talib prepared a great banquet, and slaughtered many animals, to honor the blessed new-born child.
Indeed, the party was attended by a crowd of people. They offered their congratulations, spent hours of merriment expressing their high feelings towards the new blessed child. His cousin Muhammad (S.A.W.), who used to frequent his unlce's house, where he had formerly spent the warmth of affection, and drank from the fountains of sincerity and loyalty during the year of his childhood and youth.
Holy Prophet Muhammad (S.A.W.) continued to frequent his uncle's house, although he was now a married man, living with his wife, Khadija, in their own house. He cherished Ali and surrounded him with affection and care, speaking to him tenderly, rocking his cradle or carrying him in his arms.
Days passed quickly as the new blessed child grew up in the arms of his parents: Abu-Talib and Fatima and his cousin, Muhammad (S.A.W.).
