"Abu Humaid, Abu Usaid, Sahl bin Sa'd, and Muhammad bin Maslamah were once together and they were mentioning the Salat of Messenger of Allah. Abu Humaid said: 'I am the most knowledgeable among you of the Salat of Messenger of Allah: Messenger of Allah would bow and place his hands on his knees as if he was grasping them, and he would draw his forearms to hold them away from his sides.'"  

اجْتَمَعَ أَبُو حُمَيْدٍ وَأَبُو أُسَيْدٍ وَسَهْلُ بْنُ سَعْدٍ وَمُحَمَّدُ بْنُ مَسْلَمَةَ فَذَكَرُوا صَلاَةَ رَسُولِ اللَّهِ ﷺ فَقَالَ أَبُو حُمَيْدٍ أَنَا أَعْلَمُكُمْ بِصَلاَةِ رَسُولِ اللَّهِ ﷺ إِنَّ رَسُولَ اللَّهِ ﷺ رَكَعَ فَوَضَعَ يَدَيْهِ عَلَى رُكْبَتَيْهِ كَأَنَّهُ قَابِضٌ عَلَيْهِمَا وَوَتَّرَ يَدَيْهِ فَنَحَّاهُمَا عَنْ جَنْبَيْهِ قَالَ وَفِي الْبَابِ عَنْ أَنَسٍ  

“Abu Humaid, Abu Usaid As-Sa’di, Sahl bin Sa’d, and Muhammad bin Maslamah came together and spoke about the prayer of the Messenger of Allah ﷺ. Abu Humaid said: ‘I am the most knowledgeable of you about the prayer of the Messenger of Allah ﷺ. The Messenger of Allah ﷺ stood up and said Allahu Akbar, and raised his hands, then he raised them when he said Allahu Akbar for Ruku’, then he stood up and raised his hands, and stood straight until every bone had returned to its place.’”  

اجْتَمَعَ أَبُو حُمَيْدٍ وَأَبُو أُسَيْدٍ السَّاعِدِيُّ وَسَهْلُ بْنُ سَعْدٍ وَمُحَمَّدُ بْنُ مَسْلَمَةَ فَذَكَرُوا صَلاَةَ رَسُولِ اللَّهِ ﷺ فَقَالَ أَبُو حُمَيْدٍ أَنَا أَعْلَمُكُمْ بِصَلاَةِ رَسُولِ اللَّهِ ﷺ إِنَّ رَسُولَ اللَّهِ ﷺ قَامَ فَكَبَّرَ وَرَفَعَ يَدَيْهِ ثُمَّ رَفَعَ حِينَ كَبَّرَ لِلرُّكُوعِ ثُمَّ قَامَ فَرَفَعَ يَدَيْهِ وَاسْتَوَى حَتَّى رَجَعَ كُلُّ عَظْمٍ إِلَى مَوْضِعِهِ  

Abu Humaid, Abu Usaid, Sahl. B Sa’d and Muhammad b. Maslamah (once) got together and discussed how the Messenger of Allah ﷺ used to offer his prayer. Abu Humaid said: I am more informed than any of you regarding the prayer offered by the Messenger of Allah ﷺ. Then he mentioned a part of it, and said: He then bowed and placed his hands upon his knees as if he caught hold of them; and bent them, keeping (his arms) away from his sides. He them prostrated himself and placed his nose and forehead (on the ground); and kept his arms away from his side, and placed his palms (on the ground opposite his shoulders; he then raised his head that every bone returned to its proper place; (he then prostrated twice) until he finished this prostrations). Then he sat down and spread out his left foot, putting forward the front of his right foot towards the qiblah placing the palm of his right hand on his right knee, and the palm of his left hand on his left knee, and he pointed with his finger. Abu Dawud said: This tradition has been narrated by Ibn al-Mubarak from Fulaih who heard ‘Abbas . Sahl narrating it; but I do not remember it. I think he made the mention of ‘Isa b. ‘Abd Allah who heard ‘Abbas b. Sahl saying: I accompanied Abu Humaid al-Sa’idi. (Using translation from Abū Dāʾūd 734)   

اجْتَمَعَ مُحَمَّدُ بْنُ مَسْلَمَةَ وَأَبُو حُمَيْدٍ وَأَبُو أُسَيْدٍ وَسَهْلُ بْنُ سَعْدٍ فَذَكَرُوا صَلَاةَ رَسُولِ اللهِ ﷺ فَقَالَ أَبُو حُمَيْدٍ أَنَا أَعْلَمُكُمْ بِصَلَاةِ رَسُولِ اللهِ ﷺ إِنَّ رَسُولَ اللهِ ﷺ قَامَ فَكَبَّرَ وَرَفَعَ يَدَيْهِ ثُمَّ رَفَعَ يَدَيْهِ حِينَ كَبَّرَ لِلرُّكُوعِ ثُمَّ رَكَعَ ثُمَّ وَضَعَ يَدَيْهِ عَلَى رُكْبَتَيْهِ كَأَنَّهُ قَابِضٌ عَلَيْهِمَا وَوَتَّرَ يَدَيْهِ فَنَحَّاهُمَا عَنْ جَنْبَيْهِ وَلَمْ يُصَبِّ رَأْسَهُ وَلَمْ يُقْنِعْهُ ثُمَّ رَفَعَ يَدَيْهِ فَاسْتَوَى قَائِمًا حَتَّى أَخَذَ كُلُّ عَظْمٍ مَوْضِعَهُ ثُمَّ سَجَدَ وَأَمْكَنَ جَبْهَتَهُ وَأَنْفَهُ وَنَحَّى يَدَيْهِ عَنْ جَنْبَيْهِ وَوَضَعَ كَفَّيْهِ حَذْوَ مَنْكِبَيْهِ حَتَّى فَرَغَ ثُمَّ جَلَسَ فَافْتَرَشَ رِجْلَهُ الْيُسْرَى وَأَقْبَلَ بِصَدْرِ الْيُمْنَى عَلَى قِبْلَتِهِ وَوَضَعَ يَدَهُ الْيُسْرَى عَلَى رُكْبَتِهِ الْيُسْرَى وَيَدَهُ الْيُمْنَى عَلَى رُكْبَتِهِ الْيُمْنَى وَأَشَارَ بِإِصْبَعِهِ
