The Prophet (ﷺ) sacrificed two horned rams which were white with black markings and had been castrated. When he made them face the qiblah, he said: I have turned my face towards Him. Who created the heavens and the earth, following Abraham's religion, the true in faith, and I am not one of the polytheists. My prayer, and my service of sacrifice, my life and my death are all for Allah, the Lord of the Universe, Who has no partner. That is what I was commanded to do, and I am one of the Muslims. O Allah it comes from Thee and is given to Thee from Muhammad and his people. In the name of Allah, and Allah is Most Great. He then made sacrifice.
Sunan Abi Dawud Book 16, Hadith 8
Yahya related to me from Malik from Zayd ibn Aslam from his
father that Umar ibn al-Khattab prayed two rakas with the people of
Makka, and then, when he had finished, he said, "People of Makka,
complete your prayer, becausewe are a group of travellers." Later,
Umar prayed two rakas 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 Makka should pray two rakas at Arafa or four,
and whether the amir of the hajj, if he was a Makkan, should pray
dhuhr and asr with four rakas or two, and also how the people of Makka
who were living (at Mina) should pray, and he said, "The people of
Makka should pray only two rakas 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."
Muwatta Malik Book 20, Hadith 215
