Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with them both) said: "The Sunnah is that the Imam leads Zuhr, Asr, Maghrib, Isha and Fajr at Mina; then he goes to Arafah and takes a midday rest wherever he finds a place, until, when the sun has passed the meridian, he addresses the people; then he prays Zuhr and Asr together. Then he stays at Arafat until the sun sets; then he departs from there and prays at Muzdalifah, or wherever Allah wills; then he stays at Jam' until, when it becomes bright, he departs before sunrise. When he has stoned the Jamrah, everything that was forbidden to him becomes lawful for him except women and perfume, until he visits the House (of Allah)."
