Sunan Ibn Majah, Chapter: The Chapters on Hajj

that the Messenger of Allah (saw) used to stop at Arafat in Namirah Valley. When Hajjaj killed Ibn Zubair, he sent word to Ibn Umar asking: "At what hour did the Prophet (saw) go out on this day?" He said: "When that time comes, we will go out." So Hajjah sent a man to watch for the time when they went out. When Ibn Umar wanted to set out, he said: "Has the sun passed the zenith?" They said: "It has not passed the zenith yet." So he sat down. Then he said: "Has the sun passed the zenith?" They said: "It has not passed the zenith yet." So he sat down. Then he said: "Has the sun passed the zenith?" They said: "Yes." When they said that it had passed the zenith, he set out.
