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.‏

The Sahabah (may Allah be pleased with them) were the keenest of people to teach the Muslims about their religion, and prayer was their top priority and foremost concern. In this hadith, the Tabi‘i Abu Qilabah ‘Abdullah ibn Zayd tells us that Malik ibn al-Huwayrithused to teach them how the Prophet (blessings and peace of Allah be upon him) prayed in practical terms, by demonstrating it to them. The apparent meaning of this report indicates that he (may Allah be pleased with him) showed them how each essential part of the prayer was to be done, and he did not teach them that at the time of prayer; rather it was at a time other than the time of prayer, so his prayer was a voluntary prayer that was done with the intention of teaching; it was not an obligatory or supererogatory prayer. When he (may Allah be pleased with him) began to teach them about the prayer, he stood fully upright, then he bowed properly, meaning that he made his back level, such that if water were to be poured on his back it would stay there, as it says in the hadith ofWabisah ibn Ma‘bad (may Allah be pleased with him) that is narrated by Ibn Majah. Then he raised his head from bowing and stood up straight, returning to the same posture as before he bowed. “For a little while” means that he paused briefly between bowing and prostrating. Then Abu Qilabah told Ayyub al-Sakhtiyani, who narrated this hadith, that the prayer of Malik (may Allah be pleased with him) resembled, in the way it was done, the prayer as done by their shaykh, meaning Abu Burayd. His name was ‘Amr ibn Salimah al-Jarmi, as stated by Ayyub al-Sakhtiyani. When the Sahabi ‘Amr ibn Salimah (may Allah be pleased with him) raised his head from the final prostration – which means the second prostration in the odd-numbered rak‘ahs – he would sit up straight, meaning that he (may Allah be pleased with him) would sit up completely, and did not get up from prostration immediately. This is what is called jalsat al-istirahah (the sitting of rest), and it was said that this is the completion of the rak‘ah. It was also said that the Prophet (blessings and peace of Allah be upon him) did that for a reason, either old age or sickness. It was also said that it is, in fact, intended to be part of the prayer, but it should be brief. Then ‘Amr (may Allah be pleased with him) got up for the final rak‘ah, to complete his prayer. This hadith indicates that one should pause and be at ease in each of the essential parts of the prayer. It indicates that it is encouraged to learn and teach others. It indicates that the jalsat al-istirahah (the sitting of rest) is permissible..
