Hadith 1914
Sayyiduna Ibn Umar (may Allah be pleased with them both) said: When we set out from Mina (towards Arafat) with the Noble Prophet (peace and blessings be upon him), some of us were reciting the takbir and some of us were calling out the talbiyah.
Hadith 1915
Muhammad bin Abi Bakr al-Thaqafi said: While going from Mina to Arafat, I asked Sayyiduna Anas bin Malik (may Allah be pleased with him) about the Talbiyah, "What would you people say along with the Messenger of Allah (peace and blessings be upon him)?" He replied: If someone proclaimed the Talbiyah, no objection was raised against him, and if someone proclaimed the Takbir, he was not prevented from doing so.
