The bowing, the prostrations, the period of standing after bowing and the interval between the two prostrations of the Prophet ﷺ used to be equal in duration .  

كَانَ رُكُوعُ النَّبِيِّ ﷺ وَسُجُودُهُ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَبَيْنَ السَّجْدَتَيْنِ قَرِيبًا مِنَ السَّوَاءِ  

He saw the Prophet ﷺ raise his hands when praying, when he bowed, when he raised his head from bowing, when he prostrated and when he raised his head from prostrating, until they were in level with the top part of his ears.  

أَنَّهُ رَأَى النَّبِيَّ ﷺ رَفَعَ يَدَيْهِ فِي صَلاَتِهِ وَإِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَإِذَا سَجَدَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ السُّجُودِ حَتَّى يُحَاذِيَ بِهِمَا فُرُوعَ أُذُنَيْهِ  

"The Salat of Messenger of Allah (was such that) when he bowed, and when he raised his head from bowing, and when he prostrated, and when he raised his head from prostration it (all) was nearly the same."  

كَانَتْ صَلاَةُ رَسُولِ اللَّهِ ﷺ إِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَإِذَا سَجَدَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ السُّجُودِ قَرِيبًا مِنَ السَّوَاءِ قَالَ وَفِي الْبَابِ عَنْ أَنَسٍ  

[Machine] The Messenger of Allah ﷺ used to stand up after raising his head from the bowing position until we would say, "He has stood up." And when he raised his head from prostration, he would sit between the two prostrations until we would say, "He has sat down."  

كَانَ رَسُولُ اللهِ ﷺ إِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ قَامَ حَتَّى نَقُولَ قَدْ أَوْهَمَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ السَّجْدَةِ جَلَسَ بَيْنَ السَّجْدَتَيْنِ حَتَّى نَقُولَ قَدْ أَوْهَمَ  

The bowing of the Messenger of Allah ﷺ, and when he raised his head from bowing, and his prostration, and the time between the two prostration, were almost equal in length. (Using translation from Nasāʾī 1065)   

أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَسُجُودُهُ وَمَا بَيْنَ السَّجْدَتَيْنِ قَرِيبًا مِنَ السَّوَاءِ  

The bowing of the Messenger of Allah ﷺ, and when he raised his head from bowing, and his prostration, and the time between the two prostration, were almost equal in length. (Using translation from Nasāʾī 1065)  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ «رُكُوعُهُ إِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَسُجُودُهُ وَبَيْنَ السَّجْدَتَيْنِ قَرِيبًا مِنَ السَّوَاءِ»  

[Machine] The prayer of the Messenger of Allah, ﷺ , was when he prayed, he would perform the bowing and when he raised his head from the bowing and when he prostrated and when he raised his head from the prostration between the two prostrations, it was close to the level, all of which were narrated correctly in the Hadith of Shu'bah ibn al-Hajjaj.  

كَانَتْ صَلَاةُ رَسُولِ اللهِ ﷺ إِذَا صَلَّى فَرَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَإِذَا سَجَدَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ السُّجُودِ بَيْنَ السَّجْدَتَيْنِ قَرِيبًا مِنَ السَّوَاءِ أَخْرَجَاهُ جَمِيعًا فِي الصَّحِيحِ مِنْ حَدِيثِ شُعْبَةَ بْنِ الْحَجَّاجِ
