"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: Indeed Messenger of Allah sat - meaning for Tashah-hud - he spread his left foot, and made the top of his right (foot) face the Qiblah, and he placed his right hand on his right knee, and his left hand on his left knee, and indicated with his finger - meaning the index finge.'" (Using translation from Tirmidhī 293)
اجْتَمَعَ أَبُو حُمَيْدٍ وَأَبُو أُسَيْدٍ وَسَهْلُ بْنُ سَعْدٍ وَمُحَمَّدُ بْنُ مَسْلَمَةَ فَذَكَرُوا صَلَاةَ رَسُولِ اللهِ ﷺ قَالَ أَبُو حُمَيْدٍ أَنَا أَعْلَمُكُمْ بِصَلَاةِ رَسُولِ اللهِ ﷺ فَذَكَرَ الْحَدِيثَ قَالَ فِيهِ ثُمَّ جَلَسَ فَافْتَرَشَ رِجْلَهُ الْيُسْرَى وَأَقْبَلَ بِصَدْرِ الْيُمْنَى عَلَى قِبْلَتِهِ وَوَضَعَ كَفَّهُ الْيُمْنَى عَلَى رُكْبَتِهِ الْيُمْنَى وَكَفَّهُ الْيُسْرَى عَلَى رُكْبَتِهِ الْيُسْرَى وَأَشَارَ بِإِصْبَعِهِ وَهَذَا فِي التَّشَهُّدِ الْأَوَّلِ وَلَيْسَ فِي حَدِيثِهِ ذِكْرُ التَّشَهُّدِ الْأَخِيرِ
