As for standing at Arafat, they are unanimously agreed that it is one of the pillars of Hajj, and that whoever misses it must perform Hajj from the next, and the sacrifice is in the opinion of most of them. We do not say that the sacrifice is for whoever misses it, for he is not a tamattu’ because he did not perform Hajj with his Umrah in one year, and the Sunnah is on the day of Arafat. To enter it before noon, and when the sun has passed, the Imam addresses the people, then combines noon and afternoon prayers at the beginning of noon time, then stands until the sun sets. This is what the Messenger of God, may God bless him and grant him peace, did.
