Ibn ˋAbbas narrates from the Prophet (S) that he stated:
“My daughter Fatima is the foremost of all the women of the world, past and future. She is a portion of me, the light of my eyes, the fruit of my heart and a spirit that resides in my body... Be witness that that I have granted her followers amnesty from the fire of hell.”
According to Shaykh al-Kulayni, Fatima Zahra was born 5 years after the appointment of the Prophet to his mission (bi’that). Shaykh al-Mufid places her birth at 2 years after the bi’that, and Shaykh al-Tusi has mentioned both dates. Accordingly, she lived for 8 or 11 years in Makka before she migrated to Madina, and according to Ya’qubi, two months after the hijra5, and according to Mas‟udi, in the second year of hijra, the Prophet married her to Ali b. Abu Talib.
Sunni scholars usually mention that she was born 5 years before the bi‟that, in the year that the Quraysh rebuilt the Ka‟ba. Some of them, like Hakim Nishaburi, have also mentioned that she was born a year after the bi‟that, when the Prophet was 41 years old. For detail
