Sahih Bukhari | Volume 5 | Hadith Number 207

Narrated by Qais
I heard Said bin Zaid saying to the people, "If you but saw me and Umar's sister tied and forced by 'Umar to leave Islam while he was not yet a Muslim. And if the mountain of Uhud could move from its place for the evil which you people have done to Uthman, it would have the right to do that."
