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." (Using translation from Tirmidhī 279)   

كَانَتْ صَلَاةُ رَسُولِ اللهِ ﷺ إِذَاصَلَّى فَرَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَإِذَا سَجَدَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ السُّجُودِ وَبَيْنَ 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 النَّبِيَّ ﷺ كَانَ إِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَسُجُودُهُ وَمَا بَيْنَ 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
