Yahya related to me from Malik from Zayd ibn Aslam from his father that Umar ibn al-Khattab prayed two Rak'ahs with the people of Makka, and then, when he had finished, he said, "People of Makka, complete your prayer, because we are a group of travellers." Later, Umar prayed two Rak'ahs with them at Mina, but we have not heard that he said anything to them on that occasion. Malik was asked whether the people of Makkah should pray two Rak'ahs at Arafa or four, and whether the amir of the hajj, if he was a Makkan, should pray Dhuhr and Asr with four Rak'ahs or two, and also how the people of Makkah who were living (at Mina) should pray, and he said, "The people of Makkah should pray only two Rak'ahs at Arafa and Mina for as long as they stay there, and should shorten the prayer until they return to Makka. The amir of the hajj, if he is a Makkan, should also shorten the prayer at Arafa and during the days of Mina. Anyone who is living at Mina as a resident should do the full prayer at Mina, and similarly anyone who lives at Arafa and is a resident there should do the full prayer at Arafa."
