Sahih al-Bukhari 10:197
Narrated Aiyub:
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.

حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، قَالَ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ أَيُّوبَ، عَنْ أَبِي قِلاَبَةَ، قَالَ كَانَ مَالِكُ بْنُ الْحُوَيْرِثِ يُرِينَا كَيْفَ كَانَ صَلاَةُ النَّبِيِّ صلى الله عليه وسلم 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.
