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

that the Prophet ﷺ, when he sat in prayer (in tashahhud), would place his hands on his knees and raise his right finger next to the thumb, making dua with it, and he would place his left hand on his left knee, spreading it over it.

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 while I was fiddling with pebbles during the prayer. When he finished, he forbade me and said, “Do as the Messenger of Allah ﷺ used to do.” I said, “And how did the Messenger of Allah ﷺ used to do?” He said, “When he sat in the prayer, he would place his right hand on his right thigh, clench all his fingers, and gesture with the finger next to the thumb; and he would place his left hand on his left thigh.”

رَآنِي عَبْدُ اللَّهِ بْنُ عُمَرَ وَأَنَا أَعْبَثُ بِالْحَصَى فِي الصَّلاَةِ فَلَمَّا انْصَرَفَ نَهَانِي فَقَالَ 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
