It was narrated from ‘Ubaidullah, from Salim, from his father, that the Prophet ﷺ prayed Maghrib at Muzdalifah. When we halted he said:
“Prayer should be done with Iqamah.”

حَدَّثَنَا مُحْرِزُ بْنُ سَلَمَةَ الْعَدَنِيُّ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ مُحَمَّدٍ، عَنْ عُبَيْدِ اللَّهِ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، أَنَّ النَّبِيَّ ـ ﷺ ـ صَلَّى الْمَغْرِبَ بِالْمُزْدَلِفَةِ فَلَمَّا أَنَخْنَا قَالَ " الصَّلاَةُ بِإِقَامَةٍ " .
