Imam Malik's Muwatta, Chapter: Hajj

Yahya related to me from Malik, from Hisham ibn 'Urwa, that his father would stop saying the talbiya when he entered the Haram, if he was doing 'umra. Malik said that someone who went into ihram at at-Tanim should stop saying the talbiya when he saw the House. Yahya said that Malik was asked where a man from the people of Madina, or elsewhere, who had begun doing umra at one of the mawaqit, should stop saying the talbiya, and he said, "Someone who goes into ihram at one of the mawaqit should stop saying the talbiya when he arrives at the Haram." Malik added, "I have heard that Abdullah ibn Umar used to do that."
