question #2 Sahih al-Bukhari 970, Book 13, Hadith 19 : How did the companions of the Prophet express their devotion during the pilgrimage?

While we were going from Mina to `Arafat, I asked Anas bin Malik, about Talbiya, “How did you use
to say Talbiya in the company of the Prophet?” Anas said: “People used to say Talbiya and their
saying was not objected to and they used to say Takbir and that was not objected to either. ”
