The prostration observed by the Messenger of Allah ﷺ, his bowing, and his sitting between the two prostrations were nearly equal.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ سُجُودُهُ وَرُكُوعُهُ وَقُعُودُهُ وَمَا بَيْنَ السَّجْدَتَيْنِ قَرِيبًا مِنَ السَّوَاءِ  

I did not offer prayer behind anyone more brief than the one offered by the Messenger of Allah ﷺ and that was perfect. When the Messenger of Allah ﷺ said: “Allah listens to him who praises Him,” he stood long we thought that he had omitted something; then he say takbir(Allah is most great) and prostrate, and would sit between the two prostrations so long that we thought that he had omitted something.  

مَا صَلَّيْتُ خَلْفَ رَجُلٍ أَوْجَزَ صَلاَةً مِنْ رَسُولِ اللَّهِ ﷺ فِي تَمَامٍ وَكَانَ رَسُولُ اللَّهِ ﷺ إِذَا قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ قَامَ حَتَّى نَقُولَ قَدْ أَوْهَمَ ثُمَّ يُكَبِّرُ وَيَسْجُدُ وَكَانَ يَقْعُدُ بَيْنَ السَّجْدَتَيْنِ حَتَّى نَقُولَ قَدْ أَوْهَمَ  

I witnessed Muhammed ﷺ –Abu Kamil’s version has the wording: The Messenger of Allah ﷺ-during his prayer. I found his standing like his bowing and prostration and his moderation in bowing was like that of his prostration, and his sitting between the two prostration and his prostration(and his sitting between the salutation) and going away( after finishing the prayer) were nearly equal to one another. Abu Dawud said: Musaddad said: His bowing and his moderation in bowing and prostration, and his prostration and his sitting between the two prostrations, and his prostration and sitting between the salutation and going away (after finishing the prayer) were nearly equal.  

وَقَالَ أَبُو كَامِلٍ رَسُولَ اللَّهِ ﷺ فِي الصَّلاَةِ فَوَجَدْتُ قِيَامَهُ كَرَكْعَتِهِ وَسَجْدَتِهِ وَاعْتِدَالَهُ فِي الرَّكْعَةِ كَسَجْدَتِهِ وَجَلْسَتَهُ بَيْنَ السَّجْدَتَيْنِ وَسَجْدَتَهُ مَا بَيْنَ التَّسْلِيمِ وَالاِنْصِرَافِ قَرِيبًا مِنَ السَّوَاءِ
