Sunan Abi Dawud 987
’Abd al-Rahman al-Mu’awl said:
‘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.
حَدَّثَنَا الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنْ مُسْلِمِ بْنِ أَبِي مَرْيَمَ، عَنْ عَلِيِّ بْنِ عَبْدِ الرَّحْمَنِ الْمُعَاوِيِّ، قَالَ رَآنِي عَبْدُ اللَّهِ بْنُ عُمَرَ وَأَنَا أَعْبَثُ بِالْحَصَى فِي الصَّلاَةِ فَلَمَّا انْصَرَفَ نَهَانِي وَقَالَ اصْنَعْ كَمَا كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَصْنَعُ ‏.‏ فَقُلْتُ وَكَيْفَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَصْنَعُ قَالَ كَانَ إِذَا جَلَسَ فِي الصَّلاَةِ وَضَعَ كَفَّهُ الْيُمْنَى عَلَى فَخِذِهِ الْيُمْنَى وَقَبَضَ أَصَابِعَهُ كُلَّهَا وَأَشَارَ بِأُصْبُعِهِ الَّتِي تَلِي الإِبْهَامَ وَوَضَعَ كَفَّهُ الْيُسْرَى عَلَى فَخِذِهِ الْيُسْرَى ‏.‏
