Sahih Muslim Book 7, Hadith Number 2936.

Chapter : The pilgrim should continue to pronounce Talbiya until the stoning of Jamrat al-‘Aqaba on the day of sacrifice (10th of Dhu’l-Hajja).

‘Abd al-Rahman b. Yazid and al-Aswad b. Yazid reported: We heard ‘Abdullah b. Mas’ud saying to the gathering of people (at Muzdalifa) that he had heard Talbiya from him, upon whom Surah al-Baqara was revealed, at this very place. And so he (‘Abdullah b. Mas’ud) pronounced Talbiya and we also pronounced it with him.
