Narrated Abu Huraira:
The Prophet (ﷺ) 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 Messenger (ﷺ), 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. "
