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.  

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  

Jabir bin ‘Abdallah reported the Apostle of Allaah ﷺ as saying “The whole of ‘Arafah is a place of halting, the whole of Mina is a place of sacrifice, the whole of Al Muzdalifah is a place of halting and all the passes of Makkah are a thoroughfare and a place of sacrifice. (Using translation from Abū Dāʾūd 1937)   

عَنْ رَسُولِ اللهِ ﷺ قَالَ كُلُّ عَرَفَةَ مَوْقِفٌ وَكُلُّ الْمُزْدَلِفَةِ مَوْقِفٌ وَكُلُّ مِنًى مَنْحَرٌ وَكُلُّ فِجَاجِ مَكَّةَ طَرِيقٌ وَمَنْحَرٌ  

"فِطْرُكُمْ يَوْمَ تُفْطِرُونَ، وَأضْحَاكُم يَوْمَ تُضَحُّونَ، وَكُلُّ عَرَفة مَوْقفٌ وَكُلُّ مِنًى مَنْحَرٌ، وَكُلُّ فِجَاج مَكَّةَ مَنْحَرٌ، وَكُلُّ جَمْع مَوْقِفٌ".
