Sunan An-Nasai, Chapter: The Book of the Adhan (The Call to Prayer)

from his father, that Jabir bin Abdullah said: "The Messenger of Allah (saw) traveled until he came to Arafah, where he found that the tent had been pitched for him in Namirah, so he stopped there. Then when the sun had passed its zenith he called for Qaswa'* and she was saddled for him. Then when he reached the bottom of the valley he addressed the people. Then Bilal called the Adhan, then he said the Iqamah and he prayed Zuhr, then he said the Iqamah and prayed 'Asr, and he did not offer any prayer in between them." (Sahih) *The name of the Prophet's (saw) mount which was a she-camel.
