حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم صَلَّى الْمَغْرِبَ وَالْعِشَاءَ بِالْمُزْدَلِفَةِ جَمِيعًا ‏.‏
Translation
Abdullah ibn Malik said

I offered three rak'ahs of the sunset prayer and two rak'ahs of the night prayer along with Ibn Umar. Thereupon Malik ibn al-Harith said: What is this prayer? He said: I offered these prayers along with the Messenger of Allah (ﷺ) in this place with a single iqamah.
