وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي عَوْنٍ، قَالَ سَمِعْتُ جَابِرَ بْنَ سَمُرَةَ، قَالَ عُمَرُ لِسَعْدٍ قَدْ شَكَوْكَ فِي كُلِّ شَىْءٍ حَتَّى فِي الصَّلاَةِ . قَالَ أَمَّا أَنَا فَأَمُدُّ فِي الأُولَيَيْنِ وَأَحْذِفُ فِي الأُخْرَيَيْنِ وَمَا آلُو مَا اقْتَدَيْتُ بِهِ مِنْ صَلاَةِ رَسُولِ اللَّهِ صلى الله عليه وسلم . فَقَالَ ذَاكَ الظَّنُّ بِكَ . أَوْ ذَاكَ ظَنِّي بِكَ .
Jabir b. Samura reported: 'Umar said to Sa'd: They complain against you in every matter, even in prayer. He (Sa'd) said: I prolong (standing) in the first two (rak'ahs) and shorten it in the last two, and I make no negligence in following the prayer of the Messenger of Allah (ﷺ). He ('Umar) remarked: This is what is expected of you, or, that is what I deemed of you.
