’Urwah bin Mudarras (RAA) narrated that the Messenger of Allah said: “Anyone who offered this prayer -at al-Muzdalifah- along with us, and waited with us until we returned to Mina, and he stayed at 'Arafat (on the 9th ) before that by night or day, he would have completed the prescribed duties of Hajj." Related by the five Imams. At-Tirmidhi and Ibn Khuzaimah graded it as Sahih.
