When the Messenger of Allah ﷺ sat in prayer. he placed the left foot between his thigh and shank and stretched the right foot and placed his left hand on his left knee and placed his right hand on his right thigh, and raised his finger.  

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا قَعَدَ فِي الصَّلاَةِ جَعَلَ قَدَمَهُ الْيُسْرَى بَيْنَ فَخِذِهِ وَسَاقِهِ وَفَرَشَ قَدَمَهُ الْيُمْنَى وَوَضَعَ يَدَهُ الْيُسْرَى عَلَى رُكْبَتِهِ الْيُسْرَى وَوَضَعَ يَدَهُ الْيُمْنَى عَلَى فَخِذِهِ الْيُمْنَى وَأَشَارَ بِإِصْبَعِهِ  

'Abdullah b. Zubair narrated on the authority of his father that when the Messenger of Allah ﷺ sat for supplication, i. e. tashahhud (blessing and supplication), he placed his right hand on his right thigh and his left hand on his left thigh, and pointed with his forefinger, and placed his thumb on his (milddle) finger, and covered his knee with the palm of his left hand..  

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا قَعَدَ يَدْعُو وَضَعَ يَدَهُ الْيُمْنَى عَلَى فَخِذِهِ الْيُمْنَى وَيَدَهُ الْيُسْرَى عَلَى فَخِذِهِ الْيُسْرَى وَأَشَارَ بِإِصْبَعِهِ السَّبَّابَةِ وَوَضَعَ إِبْهَامَهُ عَلَى إِصْبَعِهِ الْوُسْطَى وَيُلْقِمُ كَفَّهُ الْيُسْرَى رُكْبَتَهُ  

Ibn 'Umar reported that when the Messenger of Allah ﷺ sat for tashahhud he placed his left hand on his left knee. and his right hand on his right knee. and he raised his right finger, which is next to the thumb, making supplication in this way, and he stretched his left hand on his left knee.  

أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا جَلَسَ فِي الصَّلاَةِ وَضَعَ يَدَيْهِ عَلَى رُكْبَتَيْهِ وَرَفَعَ إِصْبَعَهُ الْيُمْنَى الَّتِي تَلِي الإِبْهَامَ فَدَعَا بِهَا وَيَدَهُ الْيُسْرَى عَلَى رُكْبَتِهِ الْيُسْرَى بَاسِطُهَا عَلَيْهَا  

When the Messenger of Allah ﷺ sat for tashahhud, he placed his left hand on his left knee and placed his right hand on his right knee, and he formed a ring like (fifty-three) and pointed with his finger of attestation.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ إِذَا قَعَدَ فِي التَّشَهُّدِ وَضَعَ يَدَهُ الْيُسْرَى عَلَى رُكْبَتِهِ الْيُسْرَى وَوَضَعَ يَدَهُ الْيُمْنَى عَلَى رُكْبَتِهِ الْيُمْنَى وَعَقَدَ ثَلاَثَةً وَخَمْسِينَ وَأَشَارَ بِالسَّبَّابَةِ  

'Abdullah b. Umar saw me playing with pebbles during prayer. After finishing the prayer he forbade me (to do it) and said: Do as the Messenger of Allah ﷺ used to do. I said: How did Messenger of Allah ﷺ do? He said that he (the Messenger of Allah) sat at tashahhud, placed his right palm on the right thigh and closed all his fingers and pointed with the help of finger next to the thumb, and placed his left palm on his left thigh.  

اصْنَعْ كَمَا كَانَ رَسُولُ اللَّهِ ﷺ يَصْنَعُ فَقُلْتُ وَكَيْفَ كَانَ رَسُولُ اللَّهِ ﷺ يَصْنَعُ قَالَ كَانَ إِذَا جَلَسَ فِي الصَّلاَةِ وَضَعَ كَفَّهُ الْيُمْنَى عَلَى فَخِذِهِ الْيُمْنَى وَقَبَضَ أَصَابِعَهُ كُلَّهَا وَأَشَارَ بِإِصْبَعِهِ الَّتِي تَلِي الإِبْهَامَ وَوَضَعَ كَفَّهُ الْيُسْرَى عَلَى فَخِذِهِ الْيُسْرَى
