Sunan Ibn Majah, Chapter: The Chapters on Hajj

"I heard Abdur-Rahman bin Ya'mur Dili say: 'I saw the Messenger of Allah (saw) when he was standing at Arafat, and some people from Najd came to him and said: "O Messenger of Allah, what is Hajj?" He said: "Hajj is 'Arafah. Whoever comes before Fajr prayer on the night of Jam', he has completed his Hajj. The days at Mina are three. 'But whosoever hastens to leave in two days, there is no sin on him and whosoever stays on, there is no sin on him.'" [2:203] Then he seated a man behind him on his mount and he started calling out these words.'"
