question #1 Sahih al-Bukhari 3867, Book 63, Hadith 92 : What challenges did early Muslims face in maintaining their faith during the time of Umar before his conversion to Islam?

I heard Sa`id 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.”
