Full Sharh — Sahih al-Bukhari 770
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي عَوْنٍ، قَالَ سَمِعْتُ جَابِرَ بْنَ سَمُرَةَ، قَالَ قَالَ عُمَرُ لِسَعْدٍ لَقَدْ شَكَوْكَ فِي كُلِّ شَىْءٍ حَتَّى الصَّلاَةِ. قَالَ أَمَّا أَنَا فَأَمُدُّ فِي الأُولَيَيْنِ، وَأَحْذِفُ فِي الأُخْرَيَيْنِ، وَلاَ آلُو مَا اقْتَدَيْتُ بِهِ مِنْ صَلاَةِ رَسُولِ اللَّهِ صلى الله عليه وسلم. قَالَ صَدَقْتَ، ذَاكَ الظَّنُّ بِكَ، أَوْ ظَنِّي بِكَ.
