Sunan Abi Dawud
حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي إِسْحَاقَ، عَنْ عَبْدِ اللَّهِ بْنِ مَالِكٍ، قَالَ صَلَّيْتُ مَعَ ابْنِ عُمَرَ الْمَغْرِبَ ثَلاَثًا وَالْعِشَاءَ رَكْعَتَيْنِ فَقَالَ لَهُ مَالِكُ بْنُ الْحَارِثِ مَا هَذِهِ الصَّلاَةُ قَالَ صَلَّيْتُهُمَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي هَذَا الْمَكَانِ بِإِقَامَةٍ وَاحِدَةٍ .
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.
