Ashhb bin 'Abdul 'Aziz أشهب بن عبد العزيز بن داود · The Book of Hajj

"We left for Arafat with the Messenger of Allah, and some of us were reciting the Talbiyah and some reciting the Takbir."

"I came to the Prophet in Jam (Al-Muzdalifah) and said: 'Is there Hajj for me?' He said: 'Whoever offers this prayer with us and observed this standing until he departed, and he departed before that from Arafat by night or by day, then his Hajj is complete. And he has completed the prescribed duties.'"
