It is narrated from Muhammad bin Abu Bakr Thaqafi that he asked Anas bin Malik (may Allah be pleased with him) while both of them were going from Mina to Arafat in the morning, "What would you people do on this day with the Messenger of Allah (ﷺ)?" Anas (may Allah be pleased with him) replied: "Some of us would be reciting Talbiyah and no one would object to him, and some would be saying Takbir and no one would object to him."
