It was narrated from Zaid bin Aslam that his father said:
I saw "Uthman (رضي الله عنه) on the day he was besieged in the place where funerals were held; if a stone were to be thrown it would not have landed anywhere but on a man"s head. And I saw "Uthman (رضي الله عنه) look out of the window beside the place where Jibreel (عليه السلام) once stood, and he said: O people, is Talhah among you? They kept quiet. Then he said: O people, is Talhah among you? They kept quiet. Then he said: O people, is Talhah among you? Talhah bin "Ubaidullah stood up and ‘Uthman (رضي الله عنه) said to him: Are you there? I did not think that you would be in a group of people, hearing me call you three times and not answering me. I adjure you by Allah, O Talhah, do you remember the day when you and I were with the Messenger of Allah (ﷺ) in such and such a place, and none of his Companions were with him except you and I. He said: Yes, ["Uthman said:] And the Messenger of Allah (ﷺ) said to you: "O Talhah, there is no Prophet but he had a companion from among his ummah who will be with him in Paradise, and this "Uthman bin "Affan (رضي الله عنه)" - meaning me - "is that companion who will be with me in Paradise.” Talhah said: By Allah, yes [I remember that]. Then he went away.
