Sunan an-Nasa'i, Book 5, Hadith 36 (In-Book) ⓘ

Al-Hakam said: "Sa'eed bin Jubair led us in prayer in Jam'. (He prayed) Maghrib, three Rak'ahs with an Iqamah, then he prayed 'Isha', two Rak'ahs. Then he mentioned that 'Abdullah bin 'Umar had done that, and he mentioned that the Messenger of Allah had done that."

أَخْبَرَنَا عَمْرُو بْنُ يَزِيدَ، قَالَ حَدَّثَنَا بَهْزُ بْنُ أَسَدٍ، قَالَ حَدَّثَنَا شُعْبَةُ، قَالَ أَخْبَرَنِي الْحَكَمُ، قَالَ صَلَّى بِنَا سَعِيدُ بْنُ جُبَيْرٍ بِجَمْعٍ الْمَغْرِبَ ثَلاَثًا بِإِقَامَةٍ ثُمَّ سَلَّمَ ثُمَّ صَلَّى الْعِشَاءَ رَكْعَتَيْنِ ثُمَّ ذَكَرَ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ فَعَلَ ذَلِكَ وَذَكَرَ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم فَعَلَ ذَلِكَ ‏.‏
