Musannaf Ibn Abi Shayba 23:202

Affan narrated to us, he said: Wuhayb narrated to us, he said: Dawud narrated to us, from Ziyad ibn Abd Allah, from Umm Hilal bint Waki’, from the wife of Uthman, she said: Uthman dozed off, and when he woke up, he said: "The people are going to kill me." I said: "No, O Commander of the Faithful." He said: "I saw the Messenger of Allah, peace and blessings of Allah be upon him, and Abu Bakr and Umar. They said: 'Break your fast with us tonight,' or he said: 'You will break your fast with us tonight.'"
