حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ مُسْلِمِ بْنِ أَبِي مَرْيَمَ، عَنْ عَلِيِّ بْنِ عَبْدِ الرَّحْمَنِ الْمُعَاوِيِّ، أَنَّهُ قَالَ رَآنِي عَبْدُ اللَّهِ بْنُ عُمَرَ وَأَنَا أَعْبَثُ بِالْحَصْبَاءِ فِي الصَّلاَةِ فَلَمَّا انْصَرَفْتُ 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 بِأَصْبُعِهِ الَّتِي تَلِي الإِبْهَامَ وَوَضَعَ كَفَّهُ الْيُسْرَى عَلَى فَخِذِهِ الْيُسْرَى وَقَالَ هَكَذَا كَانَ يَفْعَلُ .
