Narrated Abu Huraira: The Prophet said, O Bani `Abd Munaf! Buy yourselves from Allah; O Bani `Abdul-Muttalib! Buy yourselves from Allah; O mother of Az-Zubair bin Al-Awwam, the aunt of Allah's Apostle, and O Fatima bint Muhammad! Buy yourselves from Allah, for I cannot defend you before Allah. You (both) can ask me from my property as much as you like.
