Anas used to demonstrate to us the prayer of the Prophet ﷺ and while demonstrating, he used to raise his head from bowing and stand so long that we would say that he had forgotten (the prostration).  

كَانَ أَنَسٌ يَنْعَتُ لَنَا صَلاَةَ النَّبِيِّ ﷺ فَكَانَ يُصَلِّي وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ قَامَ حَتَّى نَقُولَ قَدْ نَسِيَ  

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  

Abu Qilaba said, "Malik bin Huwairith used to demonstrate to us the prayer of the Prophet ﷺ at times other than that of the compulsory prayers. So (once) he stood up for prayer and performed a perfect Qiyam (standing and reciting from the Holy Qur'an) and then bowed and performed bowing perfectly; then he raised his head and stood straight for a while." Abu Qilaba added, "Malik bin Huwairith in that demonstration prayed like this Sheikh of ours, Abu Yazid." Abu, Yazid used to sit (for a while) on raising his head from the second prostration before getting up.  

كَانَ مَالِكُ بْنُ الْحُوَيْرِثِ يُرِينَا كَيْفَ كَانَ صَلاَةُ النَّبِيِّ ﷺ وَذَاكَ فِي غَيْرِ وَقْتِ صَلاَةٍ فَقَامَ فَأَمْكَنَ الْقِيَامَ ثُمَّ رَكَعَ فَأَمْكَنَ الرُّكُوعَ ثُمَّ رَفَعَ رَأْسَهُ فَأَنْصَتَ هُنَيَّةً قَالَ فَصَلَّى بِنَا صَلاَةَ شَيْخِنَا هَذَا أَبِي بُرَيْدٍ وَكَانَ أَبُو بُرَيْدٍ إِذَا رَفَعَ رَأْسَهُ مِنَ السَّجْدَةِ الآخِرَةِ اسْتَوَى قَاعِدًا ثُمَّ نَهَضَ
