I noticed the prayer of Muhammad ﷺ and saw his Qiyam (standing), his bowing, and then going back to the standing posture after bowing, his prostration, his sitting between the two prostrations, and his prostration and sitting between salutation and going away, all these were nearly equal to one another.  

رَمَقْتُ الصَّلاَةَ مَعَ مُحَمَّدٍ ﷺ فَوَجَدْتُ قِيَامَهُ فَرَكْعَتَهُ فَاعْتِدَالَهُ بَعْدَ رُكُوعِهِ فَسَجْدَتَهُ فَجَلْسَتَهُ بَيْنَ السَّجْدَتَيْنِ فَسَجْدَتَهُ فَجَلْسَتَهُ مَا بَيْنَ التَّسْلِيمِ وَالاِنْصِرَافِ قَرِيبًا مِنَ السَّوَاءِ  

There dominated in Kufa a man whose name was men- tioned as Zaman b. al-Ash'ath, who ordered Abu 'Ubaidah b. 'Abdullah to lead people in prayer and he accordingly used to lead them. Whenever he raised his head after bowing, he stood up equal to the time that I can recite (this supplication): O Allah! our Lord! unto Thee be the praise which would fill the heavens and the earth, and that which will please Thee besides them I Worthy art Thou of all praise and glory. None can prevent that which Thou bestowest, and none can bestow that whichthou preventest. And the greatness of the great will not avail him against Thee. Hakam (the narrator) said: I made a mention of that to Abd al-Rahman ibn Abi Laila who reported: I heard al-Bara' b. 'Azib say that the prayer of the Messenger of Allah ﷺ and his bowing, and when he lifted his head from bowing, and his prostration, and between the two prostrations (all these acts) were nearly proportionate. I made a mention of that to 'Ar b. Murrah and he said: I saw Ibn Abi Laili (saying the prayer), but his prayer was not like this.  

أَنْ يُصَلِّيَ بِالنَّاسِ فَكَانَ يُصَلِّي فَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ قَامَ قَدْرَ مَا أَقُولُ اللَّهُمَّ رَبَّنَا لَكَ الْحَمْدُ مِلْءَ السَّمَوَاتِ وَمِلْءَ الأَرْضِ وَمِلْءَ مَا شِئْتَ مِنْ شَىْءٍ بَعْدُ أَهْلَ الثَّنَاءِ وَالْمَجْدِ لاَ مَانِعَ لِمَا أَعْطَيْتَ وَلاَ مُعْطِيَ لِمَا مَنَعْتَ وَلاَ يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ قَالَ الْحَكَمُ فَذَكَرْتُ ذَلِكَ لِعَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى فَقَالَ سَمِعْتُ الْبَرَاءَ بْنَ عَازِبٍ يَقُولُ كَانَتْ صَلاَةُ رَسُولِ اللَّهِ ﷺ وَرُكُوعُهُ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَسُجُودُهُ وَمَا بَيْنَ السَّجْدَتَيْنِ قَرِيبًا مِنَ السَّوَاءِ قَالَ شُعْبَةُ فَذَكَرْتُهُ لِعَمْرِو بْنِ مُرَّةَ فَقَالَ قَدْ رَأَيْتُ ابْنَ أَبِي لَيْلَى فَلَمْ تَكُنْ صَلاَتُهُ هَكَذَا  

When Matar b. Najiya dominated Kufa he ordered Abu Ubaida to lead people in prayer, and the rest of the hadith is the same.  

أَنْ يُصَلِّيَ بِالنَّاسِ وَسَاقَ الْحَدِيثَ  

While leading you in prayer I do not shorten anything in the prayer. I pray as I saw the Messenger of Allah ﷺ leading us. He (Thabit) said: Anas used to do that which I do not see you doing; when he lifted his head from bowing he stood up (so long) that one would say: He has forgotten (to baw down in prostration). And when he lifted his head from prostration, he stayed in that position, till someone would say: He has forgotten (to bow down in prostration for the second sajda).  

أَنْ أُصَلِّيَ بِكُمْ كَمَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ يُصَلِّي بِنَا قَالَ فَكَانَ أَنَسٌ يَصْنَعُ شَيْئًا لاَ أَرَاكُمْ تَصْنَعُونَهُ كَانَ إِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ انْتَصَبَ قَائِمًا حَتَّى يَقُولَ الْقَائِلُ قَدْ نَسِيَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ السَّجْدَةِ مَكَثَ حَتَّى يَقُولَ الْقَائِلُ قَدْ نَسِيَ  

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.  

مَا صَلَّيْتُ خَلْفَ أَحَدٍ أَوْجَزَ صَلاَةً مِنْ صَلاَةِ رَسُولِ اللَّهِ ﷺ فِي تَمَامٍ كَانَتْ صَلاَةُ رَسُولِ اللَّهِ ﷺ مُتَقَارِبَةً وَكَانَتْ صَلاَةُ أَبِي بَكْرٍ مُتَقَارِبَةً فَلَمَّا كَانَ عُمَرُ بْنُ الْخَطَّابِ مَدَّ فِي صَلاَةِ الْفَجْرِ وَكَانَ رَسُولُ اللَّهِ ﷺ إِذَا قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ قَامَ حَتَّى نَقُولَ قَدْ أَوْهَمَ ثُمَّ يَسْجُدُ وَيَقْعُدُ بَيْنَ السَّجْدَتَيْنِ حَتَّى نَقُولَ قَدْ أَوْهَمَ
