When Hazrat Fatima's (S.A.) birth was to take place, the Prophet (P.B.U.H.) told Khatija (S.A.) "Jabriel has given me the good news that this child which is going to be born is a daughter and all the infallible Imams will be from her generation.
Hazrat Fatima Zahra (S.A.) was born on Friday the 20th of Jamadi ussani, the fifth year of Hijrah, when Quraish were busy in constructing the building of Khana-e-Kaabah.
Training and Fostering
Fatima (S.A.) was brought up and trained in the family of Prophet (P.B.U.H) and took advantage and share of the knowledge and wisdom of the Prophet (P.B.U.H.). She heard the recitation of Quran from the Prophet (P.B.U.H.) and leant it by heart, and got busy with the idea and concept of self training and becoming a complete and real human.
She extremely loved her honorable father and the Holy Quran. She took advantage and portion from the blessings of her father's existence. These were the perfections due to which the Prophet (P.B.U.H.) loved her to the extreme.
Once his wife Ayesha (R.A.) asked him, "Do you love Fatima Zahra so much, that when she arrives you get up from your place to give respect to her and kiss her hands and make her sit next to yourself?"
He replied, "Oh Ayesha! If you come to know why I love Fatima so much, you shall also love her." He considered her the part and parcel of his life, and used to say repeatedly, "Fatima (S.A.) is a piece of me, whosoever tortures her he has tortured me, and whoever pleases her has pleased me." One day, the Prophet (P.B.U.H.) of Islam said, "Oh Fatima God gets pleased on your being pleased and gets furious due to your unhappiness and displeasure.
Fatima Zahra (S.A.), most of all resembled her father in her looks, character, behavior and conduct. Ome Salma the wife of the Prophet (P.B.U.H.) said, "Fatima Zahra resembled the Prophet (P.B.U.H.) most of all the people."
The Father-Daughter Relation
The love between the father and daughter was not a one-way process; instead, Fatima (S.A.) too immensely loved her father (Prophet) like he loved her. When Hazrat Khatija (S.A.) died, she was not more than six years of age. After the death of her mother, She always looked after the comfort of her father at home. Fatima (S.A.) was such a daughter who constantly and stably followed the footsteps of her father. The streets and Masjid-e-Haram of Mecca were full of those who teased, insulted and tortured the Prophet (P.B.U.H.). Whenever her respect worthy father returned home in the injured condition, she would wash the blood off his sacred face and dress his wounds and encouraged him with her sweet conversation.
At such times, when her father was a stranger in his own land and among his own people and he was all alone with all the relatives present, and secluded and lonely among all those who spoke the same language he spoke. Moreover, he was all-alone during his struggle and combat against ignorance, idol worshipping and he was carrying the heavy responsibility of preaching on his own.
Then it was only and only Fatima (S.A.) who pleased and consoled the heart of her father with her sincere love and affection. She by accepting the Prophecy of her father strengthened his hopes. That is the reason why the Prophet used to say, "May your father sacrifice his life upon you" or that he would call her the "mother of her father". Because, she was like a mother for her father.
