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»  

"I watched the Messenger of Allah ﷺ when he prayed, and I noticed that his standing, his bowing, his standing up after bowing, his prostration, his sitting between the two prostrations and his sitting between the taslim and departing were almost the same in length." (Using translation from Nasāʾī 1332)   

رَمَقْتُ رَسُولَ اللَّهِ ﷺ فِي صَلَاتِهِ فَوَجَدْتُ «قِيَامَهُ وَرَكْعَتَهُ وَاعْتِدَالَهُ بَعْدَ الرَّكْعَةِ فَسَجْدَتَهُ فَجِلْسَتَهُ بَيْنَ السَّجْدَتَيْنِ فَسَجْدَتَهُ وجِلْسَتَهُ بَيْنَ التَّسْلِيمِ وَالِانْصِرَافِ قَرِيبًا مِنَ السَّوَاءِ» قَالَ أَبُو مُحَمَّدٍ هِلَالُ بْنُ حُمَيْدٍ أُرَى أَبُو حُمَيْدٍ الْوَزَّانُ
