Sa’d reported that he heard his father or his uncle say ; I witnessed the Prophet ﷺ while offering prayer. He used to stay in his bowing and his prostration as long as one uttera the words “Glory be to Allah and praise be to Him” three times.  

رَمَقْتُ النَّبِيَّ ﷺ فِي صَلاَتِهِ فَكَانَ يَتَمَكَّنُ فِي رُكُوعِهِ وَسُجُودِهِ قَدْرَ مَا يَقُولُ سُبْحَانَ اللَّهِ وَبِحَمْدِهِ ثَلاَثًا  

The Prophet ﷺ said: When one of you bows, he should say three time,:"Glory be to my mighty Lord," and when he prostrates, he should say: "Glory be to my most high Lord" three times. This is the minimum number. Abu Dawud said: The chain of this tradition is broken. The narrator 'Awn did not see 'Abd Allah (b. Mas'ud).  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا رَكَعَ أَحَدُكُمْ فَلْيَقُلْ ثَلاَثَ مَرَّاتٍ سُبْحَانَ رَبِّيَ الْعَظِيمِ وَذَلِكَ أَدْنَاهُ وَإِذَا سَجَدَ فَلْيَقُلْ سُبْحَانَ رَبِّيَ الأَعْلَى ثَلاَثًا وَذَلِكَ أَدْنَاهُ  

The Messenger of Allah ﷺ said: When one of you recites "By the fig and the olive" (Surah 95) and comes to its end "Is not Allah the best judge?" (verse 8), he should say: "Certainly, and I am one of those who testify to that." When one recites "I swear by the Day of Resurrection" (Surah 75) and comes to "Is not that one able to raise the dead to life? (verse 40), he should say: "Certainly." And when one recites "By those that are sent" (Surah 77), and comes to "Then in what message after that will they believe? " (Surah 50), he should say: "We believe in Allah." The narrator Isma'il (ibn Umayyah) said: I beg to repeat (this tradition) before the Bedouin (who reported this tradition) so that I might see whether he (was mistaken). He said: My nephew, do you think that I did not remember it? I performed sixty hajj (pilgrimages); there is no hajj but I recognize the came on which I performed it.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ قَرَأَ مِنْكُمْ { وَالتِّينِ وَالزَّيْتُونِ } فَانْتَهَى إِلَى آخِرِهَا { أَلَيْسَ اللَّهُ بِأَحْكَمِ الْحَاكِمِينَ } فَلْيَقُلْ بَلَى وَأَنَا عَلَى ذَلِكَ مِنَ الشَّاهِدِينَ وَمَنْ قَرَأَ { لاَ أُقْسِمُ بِيَوْمِ الْقِيَامَةِ } فَانْتَهَى إِلَى { أَلَيْسَ ذَلِكَ بِقَادِرٍ عَلَى أَنْ يُحْيِيَ الْمَوْتَى } فَلْيَقُلْ بَلَى وَمَنْ قَرَأَ { وَالْمُرْسَلاَتِ } فَبَلَغَ { فَبِأَىِّ حَدِيثٍ بَعْدَهُ يُؤْمِنُونَ } فَلْيَقُلْ آمَنَّا بِاللَّهِ قَالَ إِسْمَاعِيلُ ذَهَبْتُ أُعِيدُ عَلَى الرَّجُلِ الأَعْرَابِيِّ وَأَنْظُرُ لَعَلَّهُ فَقَالَ يَا ابْنَ أَخِي أَتَظُنُّ أَنِّي لَمْ أَحْفَظْهُ لَقَدْ حَجَجْتُ سِتِّينَ حَجَّةً مَا مِنْهَا حَجَّةٌ إِلاَّ وَأَنَا أَعْرِفُ الْبَعِيرَ الَّذِي حَجَجْتُ عَلَيْهِ  

I did not offer behind anyone after the Messenger of Allah ﷺ a prayer like the prayer offered by the Messenger of Allah ﷺ than this youth, i.e. Umar ibn AbdulAziz. We estimated reciting glorification ten times in his bowing, and in his prostration ten times. Abu Dawud said: Ahmad b. Salih said: I asked him ('Abd Allah) whether the name Manus is correct of Mabus. He replied: 'Abd al-Razzaq used to say Mabus, but I remember Manus (i.e. the narrator Wahb b. Manus). These are the words of Ibn Rafi'. It has also been narrated by Ahmad from Sa'id b. Jubair on the authority of Anas b. Malik.  

سَمِعْتُ أَنَسَ بْنَ مَالِكٍ يَقُولُ مَا صَلَّيْتُ وَرَاءَ أَحَدٍ بَعْدَ رَسُولِ اللَّهِ ﷺ أَشْبَهَ صَلاَةً بِرَسُولِ اللَّهِ ﷺ مِنْ هَذَا الْفَتَى يَعْنِي عُمَرَ بْنَ عَبْدِ الْعَزِيزِ قَالَ فَحَزَرْنَا فِي رُكُوعِهِ عَشْرَ تَسْبِيحَاتٍ وَفِي سُجُودِهِ عَشْرَ تَسْبِيحَاتٍ
