Muwatta Imam Malik Book of Hajj, Hadith 63

Yahya related to me from Malik, from Abdullah ibn Dinar, that Abdullah ibn Umar used to say, "Anyone that does umra in the months of hajj, that is, in Shawwal, Dhu'l-Qada, or in Dhu'l-Hijja before the hajj, and then stays in Makka until the time for hajj, is doing tamattu if he then does hajj. He must sacrifice whatever animal it is easy for him to obtain, and if he cannot find one then he must fast three days during hajj and seven days when he returns."
Malik said, "This is only the case if he stays until the hajj and does hajj in that same year."
Malik said that if someone who was from Makka but had stopped living there and gone to live elsewhere, came back to do umra in the months of the hajj and then stayed in Makka to begin hajj there, he was doing tamattu, and had to offer up a sacrificial animal, or fast if he could not find one. He was not the same as the people of Makka.
Malik was asked whether someone who was not from Makka and entered Makka to do umra in the months of hajj with the intention of staying on to begin his hajj there was doing tamattu or not, and he said, "Yes, he is doing tamattu, and he is not the same as the people of Makka, even if he has the intention of staying there. This is because he has entered Makka, and is not one of its people, and making a sacrifice or fasting is incumbent on anyone who is not from Makka, and, although he intends to stay, he does not know what possibilities might arise later. He is not one of the people of Makka."
