وَحَدَّثَنِي أَبُو بَكْرِ بْنُ نَافِعٍ الْعَبْدِيُّ، حَدَّثَنَا بَهْزٌ، حَدَّثَنَا حَمَّادٌ، أَخْبَرَنَا ثَابِتٌ، عَنْ أَنَسٍ، قَالَ مَا صَلَّيْتُ خَلْفَ أَحَدٍ أَوْجَزَ صَلاَةً مِنْ صَلاَةِ رَسُولِ اللَّهِ صلى الله عليه وسلم فِي تَمَامٍ كَانَتْ صَلاَةُ رَسُولِ اللَّهِ صلى الله عليه وسلم مُتَقَارِبَةً وَكَانَتْ صَلاَةُ أَبِي بَكْرٍ مُتَقَارِبَةً فَلَمَّا كَانَ عُمَرُ بْنُ الْخَطَّابِ مَدَّ فِي صَلاَةِ الْفَجْرِ وَكَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا قَالَ " سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ " . قَامَ حَتَّى نَقُولَ قَدْ أَوْهَمَ . ثُمَّ يَسْجُدُ وَيَقْعُدُ بَيْنَ السَّجْدَتَيْنِ حَتَّى نَقُولَ قَدْ أَوْهَمَ .
English Translation
Thabit reported it on the authority of Anas:I have never said such a light and perfect prayer as I said behind the Messenger of Allah (ﷺ). The prayer of the Messenger. of Allah (ﷺ) was well balanced. And so too was the prayer of Abu Bakr well balanced. When it was the time of 'Umar b. al-Khattab he prolonged the morning prayer. When the Messenger of Allah (ﷺ) said: Allah listened to him who praised Him, he stood erect till we said: He has forgotten. He then prostrated and sat between two prostration till we said: He has forgotten
