Sahih Bukhari Volume 8, Book 81, Hadith Number 779.

Narrated By ‘Aisha : The Quraish people became very worried about the Makhzumiya lady who had committed theft. They said, “Nobody can speak (in favor of the lady) to Allah’s Apostle and nobody dares do that except Usama who is the favorite of Allah’s Apostle. ” When Usama spoke to Allah’s Apostle about that matter, Allah’s Apostle said, “Do you intercede (with me) to violate one of the legal punishment of Allah?” Then he got up and addressed the people, saying, “O people! The nations before you went astray because if a noble person committed theft, they used to leave him, but if a weak person among them committed theft, they used to inflict the legal punishment on him. By Allah, if Fatima, the daughter of Muhammad committed theft, Muhammad will cut off her hand.!”
