Zayd bin Aslam narrates from his father; he said: I was present on the day when Sayyiduna Uthman (may Allah be pleased with him) was besieged at the place of the funeral prayers. Then he (may Allah be pleased with him) said: "O Talhah! I ask you by Allah, do you remember the day when you and I were with the Messenger of Allah (peace and blessings be upon him) at such-and-such a place, and none of his (peace and blessings be upon him) Companions was there except me and you, and he (peace and blessings be upon him) said to you: 'O Talhah! Every prophet has a companion from his Ummah who will be with him in Paradise, and indeed Uthman is my companion and with me in Paradise'?" Sayyiduna Talhah (may Allah be pleased with him) replied: "By Allah, yes (I remember)." Then Sayyiduna Talhah (may Allah be pleased with him) went back from there. The chain of this hadith is sahih, but the two Shaykhs did not record it.
