Muwatta Malik, Book 20, Hadith 906 (In-Book) ⓘ

Yahya related to me from Malik from Yahya ibn Said from Adi ibn Thabit al-Ansari that Abdullah ibn Yazid al-Khatmi told him that Abu Ayyub al-Ansari told him that he prayed maghrib and isha together at Muzdalifa during the farewell hajj, with the Messenger of Allah, may Allah bless him and grant him peace.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ عَدِيِّ بْنِ ثَابِتٍ الأَنْصَارِيِّ، أَنَّ عَبْدَ اللَّهِ بْنَ يَزِيدَ الْخَطْمِيَّ، أَخْبَرَهُ أَنَّ أَبَا أَيُّوبَ الأَنْصَارِيَّ أَخْبَرَهُ أَنَّهُ، صَلَّى مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي حَجَّةِ الْوَدَاعِ الْمَغْرِبَ وَالْعِشَاءَ بِالْمُزْدَلِفَةِ جَمِيعًا ‏.‏
