Sahih Bukhari Volume 5, Book 57, Hadith Number 79.

Narated By ‘Aisha : The people of the Quraish tribe were worried about the Makhzumiya woman. They said. “Nobody dare speak to him (i.e. the Prophet) except Usama bin Zaid as he is the most beloved to Allah’s Apostle.” ‘Aisha said, “A woman from Bani Makhzumiya committed a theft and the people said, ‘Who can intercede with the Prophet for her?’ So nobody dared speak to him (i.e. the Prophet) but Usama bin Zaid spoke to him. The Prophet said, ‘If a reputable man amongst the children of Bani Israel committed a theft, they used to forgive him, but if a poor man committed a theft, they would cut his hand. But I would cut even the hand of Fatima (i.e. the daughter of the Prophet) if she committed a theft.”
