What do you think about that ..Sahih Bukhari (Volume 4, Book 53, Number 325?

stating that Narrated 'Aisha: (mother of the believers) After the death of Allah 's Apostle Fatima the daughter of Allah's Apostle asked Abu Bakr As-Siddiq to give her, her share of inheritance from what Allah's Apostle had left of the Fai (i.e. gained without fighting) which Allah had given him. Abu Bakr said to her, "Allah's Apostle said, 'Our property will not be inherited, whatever we (i.e. prophets) leave is Sadaqa (to be used for charity)." Fatima, the daughter of Allah's Apostle got angry and stopped speaking to Abu Bakr, and continued uming that attitude till she died. Fatima remained alive for six months after the death of Allah's Apostle.
