It was narrated from 'Abdullah bin Yazid that Abu Ayyub Al-Ansari told him, that during the Farewell Pilgrimage. He prayed with the Messenger of Allah ﷺ Maghrib and 'Isha' prayers together at Al-Muzdalifah. (Using translation from Nasāʾī 605)
أَنَّهُ صَلَّى مَعَ رَسُولِ اللهِ ﷺ فِي حَجَّةِ الْوَدَاعِ صَلَاةَ الْمَغْرِبِ وَالْعِشَاءِ الْآخِرَةِ بِالْمُزْدَلِفَةِ
