"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.'" (Using translation from Tirmidhī 260)   

اجْتَمَعَ مُحَمَّدُ بْنُ مَسْلَمَةَ وَأَبُو أُسَيْدٍ وَأَبُو حُمَيْدٍ وَسَهْلُ بْنُ سَعْدٍ فَذَكَرُوا صَلَاةَ رَسُولِ اللَّهِ ﷺ قَالَ أَبُو حُمَيْدٍ أَنَا أَعْلَمُكُمْ بِصَلَاةِ رَسُولِ اللَّهِ ﷺ إِنَّ رَسُولَ اللَّهِ ﷺ «قَامَ فَكَبَّرَ وَرَفَعَ يَدَيْهِ ثُمَّ رَفَعَ يَدَيْهِ حِينَ كَبَّرَ لِلرُّكُوعِ ثُمَّ رَكَعَ وَوَضَعَ يَدَيْهِ عَلَى رُكْبَتَيْهِ كَأَنَّهُ قَابِضٌ عَلَيْهِمَا وَوَتَرَ يَدَيْهِ فَنَحَّاهُمَا عَنْ جَنْبَيْهِ وَلَمْ يُصَوِّبْ رَأْسَهُ وَلَمْ يُقْنِعْهُ»
