[Machine] About the prayer of the Messenger of Allah ﷺ . He said, "Which of you can bear the prayer of the Messenger of Allah ﷺ ?" They said, "We wish to know it." He said, "The Prophet of Allah ﷺ used to pray two units of prayer after the sun had passed its zenith, equivalent to the amount of the Asr prayer from its Maghrib time. Then he would wait until the time of Duha (forenoon prayer), and he would pray four units of prayer. Then he would wait until the sun had passed its zenith and he would pray four units of prayer before Dhuhr (noon prayer), when the sun starts to decline. Then, after praying Dhuhr, he would pray two units of prayer, and before Asr, he would pray four units of prayer. Thus, it amounted to sixteen units of prayer."

عَنْ صَلَاةِ رَسُولِ اللهِ ﷺ مِنَ النَّهَارِ بَعْدَ الْمَكْتُوبَةِ؟ قَالَ وَمَنْ يُطِيقُ ذَلِكَ؟ ثُمَّ أَخْبَرَهُ قَالَ «كَانَ يُصَلِّي حِينَ تَرْتَفِعُ الشَّمْسُ رَكْعَتَيْنِ وَقَبْلَ نِصْفِ النَّهَارِ أَرْبَعَ رَكَعَاتٍ يُجْعَلُ التَّسْلِيمَ فِي آخِرِ رَكْعَةٍ وَقَبْلَ الظُّهْرِ أَرْبَعَ رَكَعَاتٍ يُجْعَلُ التَّسْلِيمَ فِي آخِرِ رَكْعَةٍ وَبَعْدَهَا أَرْبَعَ رَكَعَاتٍ يُجْعَلُ التَّسْلِيمَ فِي آخِرِ رَكْعَةٍ»  

"We asked 'Ali about the prayer of the Messenger of Allah ﷺ. He said: 'Who among you could manage to do that?' We said: 'Even if we cannot do it, we still want to hear about it.' He said: 'When the sun reached the same height (in the east) as it reaches (in the west) at the time of 'Asr, he would pray two rak'ahs, and when the sun reached the same height (in the east) as it reaches (in the west) at the time for Zuhr he would pray four Rak'ahs. He would pray four Rak'ahs before Zuhr and two after, and he would pray four Rak'ahs before 'Asr, separating each two Rak'ahs with Taslim upon the angels who are close to Allah, and the prophets, and those who follow them of the believers and Muslims."' (Using translation from Nasāʾī 874)  

عَنْ صَلَاةِ رَسُولِ اللهِ ﷺ؟ قَالَ أَيُّكُمْ يُطِيقُ ذَلِكَ قُلْتُ إِنْ لَمْ نُطِقْهُ سَمِعْنَاهُ قَالَ «إِذَا كَانَتِ الشَّمْسُ مِنْ هُنَا كَهَيْئَتِهَا عِنْدَ الْعَصْرِ صَلَّى رَكْعَتَيْنِ فَإِذَا كَانَتْ مِنْ هُنَا كَهَيْئَتِهَا مِنْ هُنَا عِنْدَ الظُّهْرِ صَلَّى أَرْبَعًا وَيُصَلِّي قَبْلَ الظُّهْرِ أَرْبَعًا وَبَعْدَهَا اثْنَتَيْنِ وَيُصَلِّي قَبْلَ الْعَصْرِ أَرْبَعًا يَفْصِلُ بَيْنَ كُلِّ رَكْعَتَيْنِ بِتَسْلِيمٍ عَلَى الْمَلَائِكَةِ الْمُقَرَّبِينَ وَالنَّبِيِّينَ وَمَنِ اتَّبَعَهُمْ مِنَ الْمُؤْمِنِينَ وَالْمُسْلِمِينَ»  

[Machine] About the prayer of the Messenger of Allah ﷺ , he said, "Verily, you will not be able to observe it." We said, "Then tell us, for we would like to know it." He said, "When the sun is about the same distance above the horizon as is the case in the Asr prayer, he would stand and pray two Rak'ahs. Then he would wait until the sun sets and pray four Rak'ahs, and then he would depart to his family and perform voluntary prayers if he desires. Then he would stand when the sun starts to decline and pray four Rak'ahs. Then he would pray two Rak'ahs after Dhuhr and four Rak'ahs before Asr."  

عَنْ صَلَاةِ رَسُولِ اللهِ ﷺ؟ قَالَ إِنَّكُمْ لَنْ تُطِيقُوهَا قُلْنَا فَأَخْبِرَنَا فَإِنَّا نُحِبُّ أَنْ نَعْلَمْهَا قَالَ «إِذَا كَانَتِ الشَّمْسُ مِنْ قِبَلِ مَشْرِقِهَا كَنَحْوٍ مِنْ صَلَاةِ الْعَصْرِ قَامَ فَصَلَّى رَكْعَتَيْنِ ثُمَّ يُمْهِلُ الشَّمْسَ حَتَّى إِذَا كَانَتْ مِنْ مَشْرِقِهَا كَنَحْوٍ مِنْ صَلَاةِ الْأُولَى صَلَّى أَرْبَعَ رَكَعَاتٍ ثُمَّ يَنْطَلِقُ إِلَى أَهْلِهِ فَيَتَنَفَّلُ إِنْ بَدَا لَهُ ثُمَّ يَقُومُ حِينَ تَمِيلُ الشَّمْسُ فَيُصَلِّي أَرْبَعَ رَكَعَاتٍ ثُمَّ يُصَلِّي بَعْدَ الظُّهْرِ رَكْعَتَيْنِ وَقَبْلَ الْعَصْرِ أَرْبَعَ رَكَعَاتٍ»  

The Messenger of Allah ﷺ used to pray two rakʿahs following every prescribed prayer, except Fajr and ‘Asr. (Using translation from Aḥmad 1226)   

كَانَ رَسُولُ اللهِ ﷺ «يُصَلِّي دُبُرَ كُلِّ صَلَاةٍ مَكْتُوبَةٍ رَكْعَتَيْنِ إِلَّا الْعَصْرَ وَالصُّبْحَ»
