حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا حَفْصُ بْنُ غِيَاثٍ، عَنْ جَعْفَرِ بْنِ مُحَمَّدٍ، عَنْ أَبِيهِ، عَنْ جَابِرٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ وَقَفْتُ هَا هُنَا بِعَرَفَةَ وَعَرَفَةُ كُلُّهَا مَوْقِفٌ وَوَقَفْتُ هَا هُنَا بِجَمْعٍ وَجَمْعٌ كُلُّهَا مَوْقِفٌ وَنَحَرْتُ هَا هُنَا وَمِنًى كُلُّهَا مَنْحَرٌ فَانْحَرُوا فِي رِحَالِكُمْ "
Jabir reported the Prophet (ﷺ) as saying "I halted here in "Arafah and the whole of "Arafah is a place of halting. I halted here in Al Muzdalifah and the whole of Al Muzdalifah is a place of halting. I sacrificed the animals here and the whole of Mina is a place of sacrifice. So sacrifice in your dwellings.
