Narrated AbuHurayrah:

The Prophet ﷺ said: The end of Ramadan is on the day when you end it, and the 'Id (festival) of sacrifice is on the day when you sacrifice. The whole of Arafah is the place of staying, and the whole of Mina is the place of sacrifice, and all the roads of Mecca are the place of sacrifice, and the whole of Muzdalifah is the place of staying.

حَدَّثَنَا مُحَمَّدُ بْنُ عُبَيْدٍ، حَدَّثَنَا حَمَّادٌ، - فِي حَدِيثِ أَيُّوبَ - عَنْ مُحَمَّدِ بْنِ الْمُنْكَدِرِ، عَنْ أَبِي هُرَيْرَةَ، ذَكَرَ النَّبِيَّ ﷺ فِيهِ قَالَ " وَفِطْرُكُمْ يَوْمَ تُفْطِرُونَ وَأَضْحَاكُمْ يَوْمَ تُضَحُّونَ وَكُلُّ عَرَفَةَ مَوْقِفٌ وَكُلُّ مِنًى مَنْحَرٌ وَكُلُّ فِجَاجِ مَكَّةَ مَنْحَرٌ وَكُلُّ جَمْعٍ مَوْقِفٌ " .
