Narrated Marwan bin Al-Hakam: `Uthman bin `Affan was afflicted with severe nose-bleeding in the year when such illness was prevelant and that prevented him from performing Hajj, and (because of it) he made his will. A man from Quraish came to him and said, Appoint your successor. `Uthman asked, Did the people name him? (i.e. the successor) the man said, Yes. `Uthman asked, Who is that? The man remained silent. Another man came to `Uthman and I think it was Al-Harith. He also said, Appoint your successor. `Uthman asked, Did the people name him? The man replied Yes. `Uthman said, Who is that? The man remained silent. `Uthman said, Perhaps they have mentioned Az-Zubair? The man said, Yes. `Uthman said, By Him in Whose Hands my life is, he is the best of them as I know, and the dearest of them to Allah's Apostle .
