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.
