حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَنْبَأَنَا سُفْيَانُ عَنْ عَبْدِ الْمَلِكِ بْنِ عُمَيْرٍ عَنْ جَابِرِ بْنِ سَمُرَةَ قَالَ شَكَا أَهْلُ الْكُوفَةِ سَعْدًا إِلَى عُمَرَ فَقَالُوا لَا يُحْسِنُ يُصَلِّي قَالَ فَسَأَلَهُ عُمَرُ فَقَالَ إِنِّي أُصَلِّي بِهِمْ صَلَاةَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَرْكُدُ فِي الْأُولَيَيْنِ وَأَحْذِفُ فِي الْأُخْرَيَيْنِ قَالَ ذَلِكَ الظَّنُّ بِكَ يَا أَبَا إِسْحَاقَ
مسند امام احمد بن حنبل · Hadith 1518
It was narrated that Jabir said: The people of Koofah complained to 'Umar about Saad and said: He does not pray properly. 'Umar asked him and he said: I lead them in prayer as the Messenger of Allah (PBUH) prayed; I make it long in the first two ( rak’ahs ) and I make it brief in the last two. He said: That is what I thought you would do, O Abu Ishaq.
