"I arrived in Al-Madinah and I said, 'Let me look at the Salat of Messenger of Allah.' When he sat - meaning for At-Tashah-hud - he spread his left foot, and placed his left hand - meaning on his left thigh - and held his right foot erect."  

الترمذي:٢٩٢حَدَّثَنَا أَبُو كُرَيْبٍ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ إِدْرِيسَ حَدَّثَنَا عَاصِمُ بْنُ كُلَيْبٍ الْجَرْمِيُّ عَنْ أَبِيهِ عَنْ وَائِلِ بْنِ حُجْرٍ قَالَ

قَدِمْتُ الْمَدِينَةَ قُلْتُ لأَنْظُرَنَّ إِلَى صَلاَةِ رَسُولِ اللَّهِ ﷺ فَلَمَّا جَلَسَ يَعْنِي لِلتَّشَهُّدِ افْتَرَشَ رِجْلَهُ الْيُسْرَى وَوَضَعَ يَدَهُ الْيُسْرَى يَعْنِي عَلَى فَخِذِهِ الْيُسْرَى وَنَصَبَ رِجْلَهُ الْيُمْنَى  

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ وَالْعَمَلُ عَلَيْهِ عِنْدَ أَكْثَرِ أَهْلِ الْعِلْمِ وَهُوَ قَوْلُ سُفْيَانَ الثَّوْرِيِّ وَأَهْلِ الْكُوفَةِ وَابْنِ الْمُبَارَكِ
