‘Abd Allah b. ‘Umar saw me playing with pebbles during prayer. When he finished his prayer, he forbade me (to do so) and said: Do as the Apostle ﷺ used to do. I asked him: How would the Messenger of Allah ﷺ do? He said: When he sat during the prayer (for reciting the tashahhud), he placed his right hand on his right thigh, and clenched all his fingers, and pointed with the finger which is adjacent to the thumb, and he placed his left hand on his left thigh. (Using translation from Abū Dāʾūd 987)   

وَقَالَ اصْنَعْ كَمَا كَانَ رَسُولُ اللهِ ﷺ يَصْنَعُ قُلْتُ وَكَيْفَ كَانَ رَسُولُ اللهِ ﷺ يَصْنَعُ؟ قَالَ كَانَ إِذَا جَلَسَ فِي الصَّلَاةِ وَضَعَ كَفَّهُ الْيُمْنَى عَلَى فَخِذِهِ الْيُمْنَى وَقَبَضَ بِأَصَابِعِهِ كُلِّهَا وَأَشَارَ بِإِصْبَعِهِ الَّتِي تَلِي الْإِبْهَامَ وَوَضَعَ كَفَّهُ الْيُسْرَى عَلَى فَخِذِهِ الْيُسْرَى لَفْظُ حَدِيثِ الشَّافِعِيِّ  

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. (Using translation from Muslim 580a)   

أَنَّ رَسُولَ اللهِ ﷺ كَانَ إِذَا جَلَسَ فِي الصَّلَاةِ وَضَعَ يَدَيْهِ عَلَى رُكْبَتَيْهِ وَرَفَعَ أُصْبُعَهُ الْيُمْنَى الَّتِي تَلِي الْإِبْهَامَ فَدَعَا بِهَا وَيَدُهُ الْيُسْرَى عَلَى رُكْبَتِهِ بَاسِطَهَا عَلَيْهَا  

[Machine] The Messenger of Allah ﷺ used to sit and make the tashahhud. He would place his right hand on his right thigh and his left hand on his left thigh, and he would clench his fingers together and make supplication.  

كَانَ رَسُولُ اللهِ ﷺ إِذَا قَعَدَ يَتَشَهَّدُ وَضَعَ يَدَهُ الْيُمْنَى عَلَى فَخِذِهِ الْيُمْنَى وَيَدَهُ الْيُسْرَى عَلَى فَخِذِهِ الْيُسْرَى وَعَقَدَ ثَلَاثًا وَخَمْسِينَ يَدْعُو

كَانَ رَسُولُ اللهِ ﷺ إِذَا قَعَدَ فِي الصَّلَاةِ جَعَلَ قَدَمَهُ الْيُسْرَى بَيْنَ فَخِذِهِ وَسَاقِهُ وَفَرَشَ قَدَمَهُ الْيُمْنَى وَوَضَعَ يَدَهُ الْيُسْرَى عَلَى رُكْبَتِهِ الْيُسْرَى وَوَضَعَ يَدَهُ الْيُمْنَى عَلَى رُكْبَتِهِ الْيُمْنَى وَأَشَارَ بِأُصْبُعِهِ لَفْظُ حَدِيثِ أَبِي عَبْدِ اللهِ وَفِي حَدِيثِ ابْنِ عَبْدَانَ وَوَضَعَ يَدَهُ الْيُمْنَى عَلَى رُكْبَتِهِ الْيُمْنَى وَأَشَارَ بِأُصْبُعٍ وَاحِدَةٍ
