وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى الْعَنَزِيُّ، حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ، عَنِ الْحَجَّاجِ، - يَعْنِي الصَّوَّافَ - عَنْ يَحْيَى، - وَهُوَ ابْنُ أَبِي كَثِيرٍ - عَنْ عَبْدِ اللَّهِ بْنِ أَبِي قَتَادَةَ، وَأَبِي، سَلَمَةَ عَنْ أَبِي قَتَادَةَ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُصَلِّي بِنَا فَيَقْرَأُ فِي الظُّهْرِ وَالْعَصْرِ فِي الرَّكْعَتَيْنِ الأُولَيَيْنِ بِفَاتِحَةِ الْكِتَابِ وَسُورَتَيْنِ وَيُسْمِعُنَا الآيَةَ أَحْيَانًا وَكَانَ يُطَوِّلُ الرَّكْعَةَ الأُولَى مِنَ الظُّهْرِ وَيُقَصِّرُ الثَّانِيَةَ وَكَذَلِكَ فِي الصُّبْحِ ‏.‏
Translation
Jabir b. Samura reported

The people of Kufa complained to Umar b. Khattab about Sa'd and they made a mention of his prayer. 'Umar sent for him. He came to him. He ('Umar) told him that the people had found fault with his prayer. He said: I lead them in prayer in accorance with the prayer of the Messenger of Allah (ﷺ). I make no decrease in it. I make them stand for a longer time in the first two (rak'ahs) and shorten it in the last two. Upon this 'Umar remarked: This is what I deemed of thee, O Abu Ishaq.
