Fāṭima bt. Muḥammad (a) (Arabic: فاطمة بنت محمد) was the daughter of the Prophet (s) and Lady Khadija (a) and wife of Imam 'Ali (a). Imam al-Hasan (a) and Imam al-Husayn (a) were her sons. Fatima is one of the five Ashab al-Kisa'. She is one of the 14 Infallibles based on Twelver Shi'a beliefs. She was the only woman who accompanied the Prophet (s) in the event of Mubahala with the Christians of Najran.
She did not pledge allegiance to Abu Bakr and opposed him firmly. After the confiscation of Fadak and usurpation of Imam 'Ali's right in being the Caliph, she delivered a sermon in Masjid al-Nabi, which is known as al-Khutbat al-Fadakiyya. Soon after the Prophet's demise, she passed away in Jumada l-Thania 3, 11/August 29, 632 in Medina. Then, she was buried secretly at night.
