Sahih Bukhari | Volume 8 | Hadith Number 778

Narrated by 'Aisha
Usama approached the Prophet on behalf of a woman (who had committed theft). The Prophet said, "The people before you were destroyed because they used to inflict the legal punishments on the poor and forgive the rich. By Him in Whose Hand my soul is! If Fatima (the daughter of the Prophet) did that (i.e. stole), I would cut off her hand."
